#3 Henrikh Mkhitaryan
The Armenian never really achieved those heights in English football which he was expected to during his Borussia Dortmund days. Apart from lack of creativity, he gives the ball away way too many times and always looks for the safest option when it comes to playmaking rather than try something out of the world.
The former Manchester United man joined Arsenal last January as a part of an infamous swap-deal with Alexis Sanchez. Selling him may seem a little harsh as this is his first full season at Arsenal, but it undoubtedly is a good option as he still has a contract till 2021 and still possesses a market value of between $25-30 million.
The Gunners are famous for letting contracts run down and then letting the players leave on a free transfer. The recent Aaron Ramsey to Juventus deal is a prime example of it. So they should make sure that they don't make the same mistake again and offload Mkhi in the summer.
