4) Willian – Chelsea
At around November time, Willian had more chance of being in our ‘Five Worst Signings’ list, as he could barely get into the side, despite his monster £30m move. Since winning a place in the team though, he’s impressed fans and neutrals alike with his endless work-rate and his exceptional technical ability – which allows him to retain possession in even the tightest of areas. If he could improve his shooting and final product, he could be a genuinely special player.
