Chelsea boss Jose Mourinho insists Manchester United will be under pressure to succeed this season after a big-spending summer.
Mourinho insists he is happy with his summer's transfer business
Mourinho has been cautious, while United have spent around £50m.
He said: "Manchester United's spending is something that we don't control, we don't want to control - we don't comment, we don't want to comment.
"But when we spent some millions, everybody pointed at us as the team with more responsibility to win."
He added: "This was because we were the spenders in the market.
"That's not the case this season. The only player we've bought was Florent Malouda. We are very happy with that."
United, who have had to stand back and watch Blues owner Roman Abramovich splash his millions since his arrival in England in 2003, have spent lavishly on the likes of Owen Hargreaves, Nani and Anderson, with Carlos Tevez set to follow.
But rather than cast an envious eye towards Old Trafford, Blues boss Mourinho insists he is delighted to allow the "responsibility" for success to rest on the shoulders of United counterpart Ferguson.
He said: "Every club does its own analysis of the market and their needs."
