#2 Malcom
The most controversial signing of last summer, Malcom was seemingly on his way to AS Roma from Bordeaux with the club announcing his arrival on its official Twitter handle while thousands of fans thronged the international airport to welcome him to the club.
In shocking scenes, Barcelona, however, hijacked the deal and the rest, as they say, is now history.
Malcom was one of the most in-demand young players in Europe following his exploits in Ligue 1 and it was expected that he would add a different dimension to the Barcelona attack.
However, it has not gone according to plan, as Ousmane Dembele's upturn in form has seen him installed as a firm starter at the club, with the result being that Malcom has failed to kick his Barcelona career into gear eight months after arriving.
So far this season, the 22-year-old has made just 14 appearances in all competitions, scoring three goals, while he is yet to make a start in either the Champions League or La Liga.
Evidence suggests that Malcom might not have a solid future at the Nou Camp and with suitors bound to be interested in his services, it would be imperative for the Blaugrana to part ways with him.
