Mourinho claims the pressure is on United

Mourinho said: "We have to look at every match as a big game and it's all about getting the points. There's no point in getting results in big games if we don't beat Norwich. We want to get three points in every match and it would be ridiculous getting a good result at Highbury but not taking three points from Norwich.

"It will be difficult because they're desperate for points and hard to beat. They don't lose many games and have nine draws so it will be very difficult, but my players are confident."

Mourinho will make at least one change to the side that drew at Highbury, with Wayne Bridge replacing Ricardo Carvalho. The Portuguese centre-back will be out for two to three weeks with a broken toe and, with Robert Huth still injured, William Gallas moves to partner John Terry at the heart of Chelsea's defence.

Mourinho is confident Bridge will seize his chance. He said: "Wayne is improving a lot and played very well against Newcastle and Arsenal. His condition is improving and he's getting more confident. His chance arrives in the right moment and he will be ready." Meanwhile, Chelsea today became the first football club to throw their weight behind London's 2012 Olympic bid.

Chief executive Peter Kenyon said: "Bringing the Olympics to London is something all sporting organisations in the capital can support.

"For it to come to London would be a great honour and will create a huge increase in sporting interest as well as other advantages. The bid is not just about the transformation of east London. It is just as relevant to other parts of London.

"If the bid is successful, clubs such as ourselves will clearly benefit from a better transport infrastructure for the capital and the international showcase that it gives London."

Chelsea will support the bid in a number of ways including perimeter board advertising, branding in club publications and links with the Chelsea community scheme.
