Krystian Bielik
The Polish youngster was signed by Arsene Wenger in January this year from Legia Warsaw for a fee reported to be in the region of £2.4million. an extremely talented defensive midfielder Bielik must be encouraged by the progress Francis Coquelin has made since returning from his loan spell. He was supposed to make his debut, however, that got stalled as Coquelin returned from Charlton Athletic. His fast paced development is one of the reasons that Wenger is holding back on splurging on another defensive midfielder.
