Why?
First of all that salary breaks down to £105,000 per week. Sure that's a ridiculous amount by the standards of the common man but, for a footballer, it's not huge. He isn't in the top 100 highest paid players in the Prem and is paid less than the likes of Alphonse Areola, Danny Ings, Jamie Vardy, John McGinn etc.
Secondly we paid no transfer fee for him which means he's an 11m expense over a two year period. Given his reputation prior to joining, nobody would have objected if we'd paid £15-20m to sign him on top of his wages. Yes he's paid slightly more han Eze and Henderson but we paid like £15m - 20m to sign each of those.
Thirdly, people are going way over the top writing him off this early. He's played 525 minutes for us. The season has barely started and he's getting used to the league, since when did we become so impatient as a fanbase?
