#2 Fred

In a poor season for Manchester United, their new signing, Fred has been poor too. The Brazilian had previously won 10 trophies with Shakhtar Donetsk. When he joined United, fans surely must have hoped that he would bring some trophy luck to the team.
The midfielder made 17 appearances in the Premier League and scored once. He struggled to make a difference in the midfield and attack. Perhaps, it will take some time for him to adjust to the demands of the Premier League, but there have been debutants who performed far better than him.
At one point in time, Fred was named the worst signing of the Red Devils. Former United legend Roy Keane had also slammed the midfielder's performance for the team this season. His first season with the club certainly did not go well and United will be playing in the Europa League next season after finishing 6th in the Premier League.
Now that the season has ended, Fred must step up his performance and consistency in the next or else, he could be cashed in.
