Sterling, aguero, bernardo, fernandinho, laporte. You could legitimately pick any of those 5 depending on what you value the most. Sterling and Aguero turn up in the games that matter and turn draws and losses into wins, bernardo has been our most productive player all season, fernandinho is our most important cog and laporte has been the best defensive player and the most reliable.
I could change my mind every minute between those 5 and all 5 need to be in any team of the year as there's simply nobody better in any of their positions yet I bet they don't all make it.
