People using the word bullied about Lindelof doesn't fit right for me. I would be more sympathetic if he was being bullied and it was just a lack of physical edge and aggression in his make up, but the greater issue is that he chronically refuses to engage attackers. If you had 2 world class ball winning defensive midfielders in front of him meaning all he has to do is sweep up and distribute the ball after they stop the attack he would probably look brilliant but his defensive impact without that set up is minimal, and there is next to nothing in his game to suggest he has any organizational or leadership qualities.
One of the reasons MCT is in the team is so that he can be a front screen for Lindelof on aerial balls, and whomever partners Lindelof automatically has to be the senior member of that pairing, what value does he offer Utd?
