Former Tottenham boss Harry Redknapp has questioned how successful Chelsea will be in the January market.

He wrote in the London Evening Standard:

"There's already talk of Chelsea trying to spend their way out of trouble in January but how do they find top quality ready to make an instant impact?

"Who do you buy? The best players are at Barcelona, Bayern Munich and Real Madrid and they won't leave.

"I don't know where they are going to go to get better players than the ones they have now.

"One report suggested they could go for Saido Berahino from West Brom. Is he going to improve their team? I don't think so.

"They should only go for proven quality at the highest level and it is hard to sign players like that at the best of times but especially in January."
