#7 Henrikh Mkhitaryan (£180,000-per-week)
The Mkhitaryan-Sanchez swap was the biggest transfer story in January this year, with the two players going opposite ways with no fee involved.
On his best day, Henrikh Mkhitaryan can be downright menacing and tough to handle, given his exquisite vision and playmaking skills. However, consistency is the main problem with the Armenian.
For a large part of last season, he looked out of form. He managed to grab only 1 goals and 5 assist in the 15 league games he played for United this season. He made a solid start this season but after that, it has been all downhill for the Armenian.
Arsenal seemed to have turned a blind eye towards his inconsistency when they agreed to raise the 29-year-old's pay by £40,000. As per his new contract, he earns more than established playmakers like Cesc Fabregas and Leroy Sane.
For a player who performs intermittently, a pay-rise certainly isn't an option to be considered.
