Chelsea legend Frank Lampard is backing Jose Mourinho for success at Manchester United.

The Blues legend kept tabs on all the action back home while playing in America's MLS with New York City.

Lampard, 37, told The Sun: “Jose will have a massive effect at United.

“He knows how to get a team winning by putting his own imprint on them. His personality reflects his teams and, looking from afar, Manchester United have needed that.

“They had a lot of quality in their squad but not much oomph. He has a base there but will bring in players and he will galvanise players.

“Jose gives them the X Factor — he did that at Chelsea. I know it didn't end perfectly there but I can see him succeeding at United.

“Next season will be as competitive as it has been for a while because a lot of teams have something to prove. But he is a top manager and a team like United need a top manager.

“It's brilliant for the Premier League that Jose is back.

“I had a great experience with him, especially during his first spell at Chelsea because he really helped me take my career onto the next level.

“I know what he brings to English football.

“I'm not a Manchester United fan but I don't think anyone can say they aren't licking their lips at the prospect of Mourinho, Guardiola, Klopp, Conte and Wenger all going up against each other next season."
