"The manager (Arsene Wenger) hasn't said anything to me and I don't know if I am going to play or not. I hope I don't or that everything will be resolved before then," Reyes was quoted as telling sports daily Marca on Friday.

"Obviously, if I do, it will make a move to Real a lot more difficult. But if I have to play, I will play."

The nine-times European champions have said they are only interested in signing players who would be available for all competitions. If Reyes played in Tuesday's first-leg in Zagreb he would be ineligible for Real in Europe next season.

Real have made no secret of their interest in the player, who cost Arsenal a reported 20 million pounds (37.45 million dollars) in January 2004, though sports director Predrag Mijatovic said on Wednesday he was not an immediate priority for them.

Despite denying reports a week ago that he wanted a move back to Spain, Reyes went on to add: "I know the people (at Arsenal) want me and the fans are with me but I haven't adapted to the life there.

"I miss Spain and I have a unique opportunity to return with what Real are offering. Everyone has to understand I can't let this chance slip away. Real Madrid are unique.

"I don't know what is happening but I am a little unsettled by all the rumours."
