Bayern Munich winger Arjen Robben spoke about his departure from Chelsea in the summer of 2007 in a television interview ahead of tonight's game.
The Dutchman also discussed how both teams are overdue a victory in the competition.
'I've never come back [to Chelsea] and that's always something I really regret,' Robben said. 'In football it all goes very quick and at the time there was no time to say goodbye.
'In one day it was the morning and we had a friendly game and in the evening I was gone. I never had the time to say goodbye to the fans and that is something I regret still, but they know how I think about Chelsea, about the club and also the fans, it's always been a really good relationship.'
On the prospect of lifting the European Cup today, he said:
'Of course I think it's my turn and I think Bayern's turn. I think not everybody will agree, especially the Chelsea fans. In the last nine years, six times they have been in the semi-finals and for them it is also time to win it.'
