He is well known in Brazil as the manager who tried to introduce the
libero position in Brazilian football.[3] He used the
3–5–2 scheme during the
1990 FIFA World Cup, but it was a failure, and
Brazil was eliminated in the second round by
Argentina.[3]
When he was the Brazil national team head coach, in 35 matches, he won 21, drew seven and lost seven.[3]
He took over the Qatar national team on 1 August 2011 as a replacement for
Milovan Rajevac, but was ultimately fired four months later as a result of the team's unimpressive performances. The
QFA highlighted his failure to advance past the group stage of the
2011 Pan Arab Games, which Qatar had hosted, as a main cause of his sacking. His record with the team ended with two wins, five draws and two losses.[5] He was officially sacked on 3 January 2012 after his contract was released by QFA.
Lazaroni was last in charge of
Qatar SC for the third time in his career following spells with the
Doha based club between 2008 and 2011 and 2012 and 2014.[2] His third spell ended in disappointment and he was dismissed in May 2016 after the club's relegation from
Qatar Stars League.
