Manchester United midfielder Paul Scholes admits the club still remembers Jose Mourinho's celebrations when his Porto won at Old Trafford.

Mourinho returns to Old Trafford as a European coach for the first time since his Porto team knocked them out five years ago.

Mourinho danced down the touchline that night in celebration, something that his friend and rival Ferguson has never forgotten. Nevertheless, there is little chance of United boss Sir Alex Ferguson performing a similar routine if United gain revenge.

Scholes said: "At his age? He'd probably collapse. 'It would be nice to see, but I don't think our manager goes in for that type of thing. He will probably stand up, have a little clap and be pleased we have gone through."
