Sanchez knows he is the only world class player in the team, possibly with the exception of Ozil, who hasn't been at that level much this season.
So he has to compensate by doing a lot of the work and dictating the play himself.
This means that he then ends up being out of position himself and diluting what he should be doing in his preferred position.
We must get him at least two top quality attacking players to play with him.
We need a replacement foe Cazorla and, if Sanchez is going to be our main striker, a top quality winger.
If we have any more performances like against Watford, we will be looking for more than just two top quality players, we will be looking for a replacement for Sanchez as well.
