Tottenham manager Harry Redknapp could face disciplinary action from UEFA after he appeared to aim a clenched-fist gesture towards Shamrock Rovers supporters during tonight's 4-0 win at Tallaght Stadium.
Goals from Steven Pienaar, Andros Townsend Jermain Defoe and Harry Kane gave Tottenham a resounding win over the Irish part-timers, but Rubin Kazan's 1-1 draw at PAOK Salonika meant Redknapp's team crashed out of the Europa League.
The 64-year-old's night took a turn for the worse with 20 minutes left when he appeared to make the angry gesture towards the Rovers fans, who had barracked him almost continuously throughout the match.
The Spurs boss, who was this week warned by the Football Association over his future conduct after making critical comments about referee Chris Foy, tried to downplay the apparent incident after the game.
When asked if had made an obscene gesture towards the Rovers fans, Redknapp said: "Not really. Did I make an "obscene" gesture? No, I didn't make... No."
Redknapp had taken heavy criticism from the Rovers fans all night, but tried again to play down the incident by saying: "I have spent enough time in Ireland to know what lovely people they are.
"If you go and meet them afterwards they are probably lovely people. But they get together and shout a load of nonsense and that is football. That's life. I don't hold any grudges."
Departing manager Michael O'Neill, who is believed to have an interview for the vacant Northern Ireland job next week, admited Spurs were a class apart.
"We were playing against a better team with better players," he said. "I thought we played well in the early part of the game but the goal set us back.
"It's disappointing. In the second half we did well, but we have to be honest and say we were well beaten by the better team."
O'Neill admits he is sad to be leaving Tallaght Stadium after a successful three-year period in which he has won back-to-back titles and made Rovers the first League of Ireland club to qualify for the groups stages of a European competition.
"The three years have been fantastic," he added. "The season before I came here they finished seventh in the league and were 42 points behind the winners. Since then we have won the cup and the league on two occasions."
