Jose Mourinho is at the centre of a police investigation over claims that he punched a fan after last night's Champions League defeat at Manchester United.
It has been alleged that the Inter Milan boss struck a supporter outside Old Trafford shortly before midnight.
However, an Inter spokesman this morning said: 'As far as we are concerned nothing happened. The coach wassurrounded by several hundred people and Jose was simply making his wayback to it so they could go to the airport.
''We are obviously aware of this allegation as it is being reportedin the Italian media but as far as we are concerned nothing happenedand there is no truth in it at all.'
A statement from the club later read: 'At the end of the game, the Portuguese tacticiangave interviews to the European media, signed autographs, watched the penaltiesof the Roma v Arsenal game before saluting (Sir Alex) Ferguson in his office.
'After giving the last interview to Inter Channel, he entered the team bus that was parked outside the dressing rooms and hence it was a very calm post-game experience.'
The Manchester Evening News claims the supporter is from East Anglia and that he was hit because he was singing a football song Mourinho did not like.
A United source said that they believe the incident took place between Mourinho leaving the stadium and boarding the team bus. The man was not injured and did not require any medical treatment.
Mourinho this morning held a post-match training session at Inter's facility at Appiano Gentile on the outskirts of Milan before details of the alleged assault had emerged.
Greater Manchester Police have contacted United to request CCTV footage of the area and have confirmed a complaint has been made.
'At 11.55pm on Wednesday March 11 2009 a man reported he had beenpunched in the face on Sir Matt Busby Way, outside Old TraffordFootball Ground,' said a GMP spokesman. 'Police are investigating a report of common assault. Inquiries are continuing.'
United would only confirm they are aware of the allegation and are making nofurther comment.
The complaint came at the end of a bad night for Mourinho, who watched his team crash out of the Champions League following their 2-0 defeat, with Nemanja Vidic and Cristiano Ronaldo grabbing United's goals at the start of each half.
Although the former Chelsea manager was in jovial mood, shaking hands with RedDevils supporters as he made his way to the visitors' dug-out before kick-off and after half-time and enjoyed a friendly post-match chat with Sir Alex Ferguson, he came under sustained attack from the Italian media for his failure to get Inter through.
'If anyone wishes to criticise my team, they will have to fight me,' he said at one point, those comments coming via an official interpreter from Italian.
Although he has taken Inter to the top of Serie A, his relationship with the Italian media is far from smooth, a fact that has only fuelled a belief that he could one day replace Ferguson at Old Trafford.
The plane taking the Inter party back to Milan left Manchester at 12.25am last night, once Mourinho had concluded his post-match obligations and enjoyed his ritual of a meeting with Ferguson.
