The 29-year-old has made a surprise move to Old Trafford after an unhappy spell with the Magpies.

Kinnear rarely had a fit Owen at his disposal at St James' Park but told Sky Sports News: "He's right up there with the best of them.

"I like to think I played with one of the best strikers in the world in Jimmy Greaves and Michael has similar attributes.

"He's a great pro, he's very dedicated, he's a really nice lad and I'm sure Alex will get the best out of him."

Former Liverpool striker Ian Rush told Sky Sports News: "People have knocked Michael Owen all his career but he comes back bigger and better.

"People said he was finished years ago but he's a fantastic player who comes back stronger and better.

"It (the talk) won't worry him, I know the way he is and he doesn't have to prove anything anyway.

"It's a chance for Michael to get back and score some goals. He'll get chances for Manchester United and will score goals."
