Carlo Ancelotti admitted Chelsea have no chance of turning around their Champions League quarter-final against Manchester United unless they make a vast improvement on the ugly Barclays Premier League win against Wigan.
The Blues toiled to a 1-0 victory at Stamford Bridge thanks to an equally-unattractive goal from Florent Malouda.
Chelsea must make history to overturn Wednesday night's 1-0 Champions League defeat to United, who have never lost a European tie having won the first leg away from home. And on only two previous occasions has a club won a Champions League tie after being defeated in the first leg at home.
"We have to play better but this is normal," said Chelsea boss Ancelotti, who admitted his side had one eye on Tuesday's game. "To win there, we have to play at our 100%."
The Italian added: "Obviously, we have more difficulty compared to last season to score a lot of goals. We are not able to convert the chances that we create."
