Alexis gave the ball away a massive 19 times in the first-half alone at Crystal Palace.
He was visibly frustrated at times with his team-mates but failed to back that up with his own performance.
United went into halftime 2-0 down, but won 3-2 at Selhurst Park.
Calling the game, Jamie Carragher stated: "Sanchez has lost the ball 19 times in that first half. That's unbelievable.
“We're talking about a supposed world-class player. He has shown that in the Premier League.
“But it feels like I don't know where he's playing, he just pops up everywhere."
