(CNN) -- Portugal have sacked national coach Carlos Queiroz with immediate effect after just over two years in the post.
The 57-year-old -- who also held the position from 1991 to 1993 -- was dismissed after a disciplinary hearing following the recent decision to suspend Queiroz for six months for insulting officials from Portugal's anti-doping body.
Portuguese Football Federation president Gilberto Madail told reporters: " The FPF has decided unanimously to end the contract of national coach Carlos Queiroz.
"The decision was taken following recent events and after analysing the actual situation concerning the national coach."
Aside from his recent suspension, former Manchester United assistant manager Queiroz had also been under pressure following a series of poor results on the pitch.
Portugal struggled to reach the 2010 World Cup finals and were knocked out by eventual winners Spain at the last 16 stage.
And their Euro 2012 qualifying campaign has also started badly, a 4-4 home draw with Cyprus followed by a 1-0 defeat in Norway.
Sporting Lisbon coach Paulo Bento has already been tipped by the Portuguese media as the front-runner to take over from Queiroz.
