#2 Victor Lindelof
He is beginning to get a little better but when you pay a fee of €35 million for a defender, you expect him to be on the mark right away. The Swedish international took a lot of time to settle at Old Trafford. He barely played in the initial few weeks, but, injuries to Eric Bailly and Phil Jones gave him a lifeline.
He struggled to adapt to the physicality of Premier League and made a lot of errors in his early days at Old Trafford. His couple of awful mistakes against Huddersfield in the Premier League cost United the game. He has kept on making mistakes throughout the campaign and never looked comfortable at the back.
Though he was a little better in Champions League, in his 9 Premier League appearances so far, he has conceded 9 goals and won just 4 games. He was beaten easily in aerial challenges, more often than not and all in all, a very poor start to his Premier League career.
