IT'S the match that could define an entire season. In the Blue corner, Carlo Ancelotti and Chelsea who have the Holy Grail of the Champions League left to fight for.
On the Red side, Alex Ferguson, whose Manchester United side are still gunning for a treble.
Under-fire Wayne Rooney and under-pressure Fernando Torres go head to head for a place in the Champions League semi-finals at Stamford Bridge tonight.
Ancelotti will hope that misfiring Torres can rediscover the form which has seen him torment Nemanja Vidic and Manchester United in the past.
"I hope this season we can have better luck. But we have to deserve the luck. In the end, if you deserve to win, you will," he said.
While Ancelotti frets about the form of his £50m striker, Alex Ferguson has bigger fish to fry.
He shrugged off questions about Rooney's foul-mouthed outburst to a Sky Sports camera and set a remarkable three trophy target for his players.
"In the past, I used to tell myself that to win just one trophy would be great. But we have the chance to win all three," said Fergie.
