Premier League clubs spent a record £225m during this January's transfer window - £50m more than January 2008's figure of £175m - according to research.

Business advisory firm Deloitte said that it was 'surprised' that the combined total surpassed the £200m mark, despite the high level of club revenues. Dan Jones, partner in Deloitte's Sports Business Group, said: "We were surprised to see more than £200m spent in a January window for the first time, particularly after only around £30m was spent in January last year.

"However, when you scratch beneath the surface you find that around 80 per cent of the total spending of £225m is concentrated across only four clubs and spread across only six players." Image: Liverpool was one of the major spenders during the January transfer window
