Beckham will not celebrate against Manchester United

David Beckham has promised he will not celebrate if he scores against Manchester United.

After 394 appearances for the club, the England midfielder believes it would be inappropriate behaviour should he find the net for AC Milan.

United face the Italians in the Champions League at the San Siro a week tomorrow, with the return leg on March 10 at Old Trafford.

It is the first time Beckham has faced his former club and he remains grateful to the fans who backed him after he was sent off against Argentina in the 1998 World Cup.

He told Inside United: "Sometimes emotion can get the better of you when you score but I do not think I would celebrate. I respect the supporters and the club.

"The relationship I have with the fans is still important to me. I went through some difficult times but they never stopped supporting me.

"I would not have got through everything without them. To me they are the best fans in the world and the support they gave me week in, week out was incredible. Nothing will ever better that."

Beckham, on loan to Milan from Los Angeles Galaxy, has an abiding affection for the Barclays Premier League champions.

He added: "I always wish I was part of Manchester United, it is just in me. Even though I am not there any more, I am still a huge fan.

"Coming to terms with not being a United player was certainly the toughest thing I've ever had to deal with.

"When you are a Manchester United player and a Manchester United fan you never want to play for any other club.

"I always want them to do well and be successful because the club still means so much to me. I've still got season tickets and I will always keep them because I love to watch every game where possible.

"I would love to take my sons one day. United will always be such a special place to me, so we will just have to see what the future holds."

Beckham's 13-year spell at United, in which he scored 85 goals, ended in July 2003 when he moved to Real Madrid and he admits he found it difficult to cope.

The England midfielder said: "United was the club I always wanted to play for and I loved every minute of my time there. The first few years (after leaving) were hard and there were a lot of things I missed.

"When I was at Real Madrid it just never felt right to come back to Old Trafford. The thought of playing against United always gave me that sick feeling because I missed the club so much.

"But when the draw was made this time it felt as though it was the right time to go back. I felt really emotional.

"It will also be extremely emotional for myself and my family on the night. I met so many amazing people during my time there, on and off the pitch, that I am looking forward to seeing everyone again.

"It is the biggest club in the world and it is one you always want to be a part of."
