He has been considerably better than average, proced vital to saving our season and is improving substantially every game.
He's the second fastest player in the league, he's tall and physical, he has the technical proficiency given hes naturally a midfielder, he has a criminally underrated cross. Shows willingness to run beyond the line off the ball.
What attributes does he lack? Take away the name and his history and look at the player without bias and he's a near perfect fit for what Pep wants in a fullback.
