There have been plenty of surprise packages in the Premier League this season.
In August, few would have expected the likes of Aaron Ramsey and Ross Barkley to be the talk of the town, while even less would have said that Luis Suarez would have already scored 22 goals having missed the first five games of the season.
But one question remains of those players who have really stood out so far this season - how much are they now worth?
With players like Ramsey, it's likely that we will never be able to find out in real life just how much he would fetch on the open market given his commitment to Arsenal.
