I wonder why people dislike him playing so much. He obviously hasnt been as effective as he was for Arsenal but there are some areas where he improved the team.
For instance Sanchez averages 3 key passes per 90 minutes this season. Pogba and Martial average 1.4 per 90 minutes. So he's over twice as likely to give the ball to a player for a shot at goal.
He averages 1.2 successful dribbles per 90, very slightly ahead of Martial's 1.1
He's also fouled 2 times per 90 mins, while Martial is fouled 1 time.
Sanchez does have a very low pass percentage at just 73% with only Ashley Young around the same, and all our other players being in the 80%+ category
He obviously isnt as fast as Martial and Martial has been finding the goal in recent times. So its fair enough to prefer Martial playing on the left to Sanchez.
But there's another spot on the wing and a role behind the striker that should be up for grabs and theres no reason why Sanchez shouldnt be tried there. He's technically our most creative player afterall.
