- Alexis Sanchez (€42.5m)
Arguably one of the best players in world football at the moment, Sanchez, moved to Arsenal from Barcelona back in 2004 for a big money move. Ever since, the Chilean has become an integral part of the squad, playing in different positions for Wenger and helping Arsenal to 5 back to back victories early this season. Wenger did not think twice about spending on Sanchez who has thrived under the Frenchman’s approach to the game, scoring 33 goals in 70 league appearances so far.
