Doncaster Rovers will not lack confidence going into tonight's Championship derby against Leeds United at the Keepmoat Stadium following their impressive midweek showing against the Canaries Rovers produced a dazzling first half performance which was worthy of much more than a 1-0 interval lead.Enthused Rovers No 2 Richard O'Kelly: "We got bodies into the box and the movement from our midfield was good as was our link play."Rovers must have had around a dozen shots on goal in the first 45 minutes.Said O'Kelly: "We are always encouraging people to shoot. We play an awful lot of games in training where players are encouraged to shoot. Tuesday's game was one of those occasions which lent itself to that tactic."Our resilience and body language when we defended set-plays in the second half was first class."It will be a tough game tonight. I saw Leeds earlier in the season against Nottingham Forest, in a game at the City Ground, which they drew 1-1, and they were outstanding,"I also watched a DVD of their game at Watford and they went there and got a result. They took an early lead, which we did on Tuesday, and they showed a lot of resilience to hang on to it. They have got some strong characters in their side and they've got some good players and we'll not be taking them for granted tonight."Becchio is a threat. He's one of those players who, if he became available and you had the money, you'd certainly look at. They've got Howson and Kilkenny in midfield and they've got two experienced warriors at the back in Naylor and Collins, so they are a strong outfit."
