Cape Town - Owen Hargreaves believes Manchester United will have to improve if Jose Mourinho's return to Chelsea this weekend is to be a happy one.
United travel to Stamford Bridge on Sunday, with Mourinho's men under scrutiny over their stuttering form.
A comfortable 4-1 victory over Fenerbahce - on the back of Monday's goalless draw at rivals Liverpool - has eased the pressure at Old Trafford.
But former United midfielder Hargreaves says his old club still need to be showing more if they are to be title-challengers.
“A point away at Anfield is a good point, especially with Liverpool flying," he told BT Sport.
“But United are seventh in the league, having spent all of that money and going to Chelsea at the weekend.
"At some point they’re going to have to start winning games."
