January may be a month of restraint for most after the Christmas festivities but for Premier League clubs it has traditionally been a time to spend big.

Since the introduction of the transfer window in the 2002-03 season, Premier League clubs have spent an estimated £2.4bn on transfers in January — although last month clubs have been more reticent to spend. This season the total January outlay by top-flight clubs was just over a third of last year’s record total.
