Developed at Athletic Bilbao's
academy, he has made over 400 first-team appearances for the club, including a La Liga record of 251 consecutive games. He scored the winning goal of the
2020–21 Supercopa de España, and also conquered the
2023–24 Copa del Rey.
Born in Spain to Ghanaian parents, Williams made his full debut for the
Spain national team in 2016. In 2022, he chose to represent Ghana at international level, being selected for the
2022 World Cup as well as the
2023 Africa Cup of Nations. His younger brother
Nico also plays for Athletic Bilbao, and for Spain.
Williams began
2013–14 playing with the
farm teamBasconia who competed in the
Tercera División.[13] After suffering a knee injury in August,[14] he returned to activity in October, making his senior debut and marking it with a goal.[6] He was immediately called up to
the reserves in the
Segunda División B and by the end of the same month had played his first match and scored his first goals at that level; he spent the campaign alternating between both squads.[15]
At the start of
2014–15, Williams scored a
hat-trick for Bilbao Athletic in a 4–0 win against
Amorebieta,[16] and followed this on 7 September 2014 with another treble in a 5–1 win over
Leioa.[17] Despite only playing the first half of the season, his 13 goals from 18 appearances helped the team ascend to the
Segunda División.[18][19]
On 17 May 2015, Williams scored his first goal in the top flight, netting a
last-minute winner in a 3–2 away victory over
Elche to help Athletic come from being behind 2–0.[24] Thirteen days later, he headed a consolation goal in the 3–1 loss to
Barcelona in
the final of the
Copa del Rey at the
Camp Nou.[25] He missed the
2015 Supercopa de España victory over the same opponents three months later through injury.[26][27]
Williams scored a brace (before giving away a
penalty) in a 3–1 win away to
Betis, on 1 November 2015.[28] He repeated the feat the following match, at home against
Partizan in the
Europa League group stage (5–1).[29] Finding the net in his third match running, he scored "a phenomenal volley" to help beat
Espanyol 2–1 at the
San Mamés.[30]
During autumn 2017, Williams scored important late goals in the Europa League against
Östersund[33] and
Hertha BSC[34] to help his team finish top of
the group. On 17 January 2018, he agreed a contract renewal, running until 2025 with an incremental buyout clause of around €80 million.[35]
On 13 January 2019, Williams scored both goals in a 2–0 home
league win over
Sevilla, finding the net at San Mamés for the first time in 41 league appearances (the previous occasion being in December 2016).[36] His second, involving a turn and sprint from his own half, touch away from the goalkeeper and precise finish at high speed, was described as "incredible" – it was later awarded as the
Marca Golden Goal of the season.[37][38][3] The fixture was also his 100th successive appearance in the league,[37] only the fifth Athletic player to achieve this[39] and the first outfield player from any Spanish club to do so since
Fran in 1993; for his performances, he was named the La Liga Player of the Month.[40]
Williams signed a nine-year contract in August 2019, with his release clause set at €135 million.[41][42][3] Late in the same month he started and scored in a 2–0
Basque derby win[43] for his 122nd consecutive Spanish League game, setting a new record by an outfield player in the 21st century ahead of
goalkeeperDiego López.[44] On 24 November, he repeated the feat in a 2–1 away victory against
Osasuna, breaking a 31–game undefeated streak of the hosts at their
El Sadar Stadium; the occasion also marked his 133rd consecutive appearance in the Spanish top tier, establishing a new club record previously held by
Carmelo Cedrún.[45][46]
On 17 January 2021, Williams scored from 20 metres early into
extra time of an eventual 3–2 win over Barcelona in the
2021 Supercopa de España final.[47][48] On 11 September, he celebrated his 300th appearance for Athletic with a goal in a 2–0 victory against
Mallorca.[49][50] A week later, he became the second player to play in 200 successive Spanish league games as he started in a 0–0 draw away to defending champions
Atlético Madrid.[51] On 1 October, he set a new record outright with his 203rd consecutive appearance in the home match with
Alavés, breaking the mark set by
Juan Antonio Larrañaga of
Real Sociedad between 1986 and 1992.[52][5]
On 17 April 2022, after starting against
Celta, Williams passed the six-year mark since he last missed a league match for the club, and extended his own Spanish top-flight record of consecutive games to 224.[53] His six-year run came to an end at 251 on 29 January 2023, when he was left out of the squad for the fixture against the same opposition, a 1–0 loss.[54][55]
In January 2024, having been on international duty at the
2023 Africa Cup of Nations, Williams made the journey back to Bilbao from
Abidjan immediately after Ghana's early elimination from the tournament at the group stage was confirmed.[56] He entered as a substitute during the second half of Athletic's
Copa quarter-final against Barcelona and scored in extra time to help his side to a 4–2 win,[57] and a fifth consecutive semi-final in the competition;[58] they went on to
win the trophy for the first time in 40 years.[59]
On 24 May 2024, Athletic manager
Ernesto Valverde reported that Williams had unknowingly spent the past two years of his footballing career playing with a two-centimetre long shard of glass in his foot.[60] The glass was discovered when the latter underwent surgery to treat a painful scar on his left foot.[60]
Around the time of his Spain debut in 2016, Williams was also coveted by the
Ghana national team, being watched by their Spanish
scoutGerard Nus.[66] In 2021, having made no competitive appearances for Spain which would have tied him to his birth nation permanently, he spoke of the possibility of playing for Ghana: "My parents are from
Accra and I really enjoy going. But I wasn't born or raised there, my culture's here, and there are players for whom it would mean more. I don't think it would be right to take the place of someone who really deserves to go and who feels Ghana 100%."[5] Local media interpreted this as a rejection of any approach from the Black Stars.[67][68]
Ultimately, on 5 July 2022, Williams announced that he was making himself available for the African nation in time for the
2022 FIFA World Cup.[69][70] In September, he received his first call-up for friendlies with
Brazil and
Nicaragua.[71] He made his debut against the former, playing the second half of the 3–0 loss in
Le Havre.[72] He was selected in Ghana's squad for the finals in Qatar;[73] within the team, he took the name "Kweku" due to the day on which he was born (Wednesday), a Ghanaian custom.[74]
Williams received his Basque first name in honour of a
Caritas Internationalis worker in Bilbao who helped his parents after they arrived in Spain in the year he was born;[3] they had been advised by an unidentified lawyer to claim to be from a war-torn country, namely
Liberia, when they first entered the country.[76][5] His younger brother,
Nico, is also a footballer and a forward; he too was brought up at Athletic Bilbao.[77][3][78][5]
Williams was one of the stars of the
Amazon Prime television documentary series Six Dreams, recorded during the 2017–18 season.[79] He can speak Spanish,
Akan, Basque and English.[80][3] In 2021, he said that he and his family had lost fluency in English, but still communicated with relatives in the
Twi dialect of Akan.[5]
Williams married Patricia Morales at Begoña Basilica in Bilbao on 1 June 2024.[81][82]
