Willian - Chelsea
Chelsea splashed out £30 million for Willian, snatching him from under the noses of Premier League rivals Tottenham in the process.
Having spent such a significant sum of money, you'd have thought that Willian would have been an integral part of Jose Mourinho's first-team, right?
Wrong. The 25-year-old has thus far been restricted to a bit-part role, though he did start against Swindon Town in the Capital One Cup on Tuesday evening.
That said, it's early days in Willian's Chelsea career and Mourinho may well be bedding the samba star into his side slowly - only time will tell.
