He said: 'I think psychologically we now have the edge.You could see when we scored what a big blow that was for them. 'We won't play for a nil-nil draw in the second leg because that would be too dangerous. We will play to win the game.
'It showed great character from my players to score when Chelsea were on top and it was a great goal from Robert.
'Chelsea played the match like a European game - they played defensively and tried to stop us scoring and suck us in so they could counter attack rather than come out and play.
'Jens Lehmann feels that he was guilty for the goal but when you decide to come out there is a risk involved and he took it.'
Chelsea's World Cup-winning central defender Marcel Desailly was dismissed for two bookable offences within two minutes after stupidly blocking Lehmann's attempt to throw out and then making contact on Patrick Vieira when he was in full flow.
