Jonny Evans unsure whether Jose Mourinho will make impact at Chelsea

Manchester United defender Jonny Evans has questioned whether Chelsea manager Jose Mourinho will repeat his previous success at Stamford Bridge.

The Portuguese coach won the Premier League title in his first two seasons with the Blues from 2004, but Evans believes that no predictions can be made regarding Mourinho's potential success as yet.

"Everyone's been saying that he will make a big difference to Chelsea but we will have to wait and see if that will be the case," The Guardian quotes Evans as saying.

"He is a good manager and I am sure he will make a big impact on them. But it's maybe over the next month or two before we realise who is going to be challenging for the league."

Chelsea will face Manchester United at Old Trafford on Monday.
