5 big disappointments in Europe's top 5 leagues so far this season

#4 Malcolm (Barcelona)

Malcolm hasn't had much chance to impress the Nou Camp faithful yet

Another star from the Nou Camp, Malcolm's transfer was controversial when it went through this summer. The winger seemed to be on the verge of joining Roma, after the Italian club had reportedly agreed a deal with Bordeaux to secure his signature; within one day, Malcolm was moving to Spain instead, Barcelona having agreed a late deal with his parent club. Roma were irate but the player himself seemed happy about joining the European giants.

Ironically, though, Malcolm has barely featured so far, making only two short league appearances. His expensive signing seemed somewhat needless, given Barcelona's strength in his position.

Lionel Messi, Philippe Coutinho, and fellow youngster Ousmane Dembele appear to be ahead of him in the pecking order, with the latter having superior potential. He'll have to show the sparkling dribbling skills and strong finishing that led to his move from France if he's to stand any chance of breaking into Valverde's starting XI.
