Former Shanghai Shenhua coach Quique Sanchez Flores says Manchester United loan signing Odion Ighalo may take time to get up to speed following his shock move.

Flores has coached the 30-year-old in both China and during his spell in charge at Watford.

Despite prospering abroad, he's warned Ighalo things might not go quite as smoothly back in England: “Mainly, the problem is how they train in China. It is not the same as in England.

“Is he really ready for first-team matches in the Premier League because the physical difference is so big?

“He probably needs one month to recover the full rhythm. The good thing is he knows his body well, works hard on injury prevention and he is always working after training.

“I should say, also, that I felt in China, he gave exactly the same effort and quality as he gave me four years ago. We had the feeling in China that he could recover a high level with any team in Europe."
