It was the biggest transfer of a much-anticipated January window, with Shakhtar Donetsk midfielder Willian upping sticks from his Ukranian home to join Dagestan side Anzhi Makhachkala for €35 million. (ESPN)
Whether the move was good or not for the player and his footballing career, though, has greatly divided opinion. Many of his biggest supporters have been left disappointed with the decision, which they fear will put an end his international ambitions.
Anzhi have a project that they hope will take them to the upper echelons of the European game, but the worry is that it will take too long for a player approaching his peak years to fully benefit from their rise.
So, just why has Willian's decision to swap from Ukraine to Russia provoked such a negative reaction from many of those who have supported his cause for so long?
