The Everton midfielder was given a round of applause from his Everton teammates after delivering an explanation for his extraordinary red card during the recent victory at Manchester United.
The midfielder became the initial Premier League player to be sent off for striking a fellow player in 17 years when he slapped Michael Keane during the match. The Toffees' performance was heroic as they competed with 10 men for 85 minutes, including added time, to achieve David Moyes' initial victory at Old Trafford as a away coach in 18 attempts.
'My first apology goes to Michael Keane,' he wrote on his accounts. 'I take full responsibility for my reaction.'
Gueye was unable to secure an opportunity to converse with Moyes or his teammates at the interval. Following the match, with the away dressing room buzzing after the narrow victory, the 36-year-old asked to address the whole team and Keane in particular.
The 36-year-old may yet be disciplined by the club despite Moyes' statement that he likes his players competing with each other. The Scot has a standard disciplinary procedure for dismissals and cautions, including fines, which is likely to be implemented in Gueye's case.
Everton could be without their key midfielder until the new year. Gueye will complete a three-game ban against Newcastle, AFC Bournemouth and Forest but might be selected for Africa Cup of Nations duty by Senegal before he becomes eligible to play against the Blues on 13 December.
'Emotions can run high,' he added. 'But nothing justifies such behaviour.'
At the same time, the Manchester United defender accused United of lacking urgency in Monday's loss, which halted their winning streak at five games.
United head to Selhurst Park for Sunday's noon kickoff. 'The next game is really important now,' commented the defender. 'We have to bounce back from this performance.'
