Fraser Forster has more cause than most to be wounded by Celtic's exit from Europe. His elevation to the England set-up has come about because of performances for his club against continental opposition. Celtic's 3-0 humbling by Milan on Tuesday bounced the Scottish champions out of European competition.

The Celtic goalkeeper, though, insisted he has not yet had time to contemplate how this will affect his hopes of at least retaining an England squad place for next summer's World Cup in Brazil. Forster won his first cap during the friendly defeat to Chile this month.

"I haven't really given it any thought yet, to be honest," Forster said. "It's obviously very disappointing to be out of the Champions League. But it's just a case of doing well for Celtic now and then I will have to see what happens. The World Cup is still a long, long way away and there's plenty of club football to be played between now and then.

"I don't know how damaging it is to be out of the European environment. I'll have to wait and see really. I haven't given a lot of thought to being out of Europe because I've spent the build-up looking forward to the Milan game and we were hoping we would come through this game. Unfortunately that hasn't happened but now I need to wait and see and keep playing well for Celtic.

"It's a fantastic club to play for and I'll take it a game at a time and not worry about the World Cup. It's still seven months away."

Still, there remains the likelihood of Forster being coaxed to pastures new. Even if that does not occur in January, it would be a major surprise if the former Newcastle United man turns out for Celtic next season. "We are only just literally out of the Champions League," said Forster when asked about his future. "But this is a huge club and I've loved every minute of being here since I first walked through the door."

Uefa has opened disciplinary proceedings against Celtic for the display of an "illicit banner" before kick-off against Milan. Images of William Wallace and Bobby Sands were displayed, alongside slogans including "the terrorist or the dreamer".

The case will be heard on 11 December. Uefa has strict rules against the transmission of "any message that is not fit for a sports event, particularly messages that are of a political, ideological, religious, offensive or provocative nature".
