I did not expect much of Barkley as it was only in my eyes, a small upgrade on my previous player of Ruben Loftus-Cheek (Europa league), however I was pleasantly surprised. I used Barkley as a CDM (I know hear me out) in a 4-2-3-1 in game alongside Fabinho. Now some of you may be skeptical about using Barkley as a CDM but I can assure you he is more than up to the task. When using a Sentinel chemistry style Barkley wins nigh-on everything in the air and aside from the multiple flashback Ibrahimovic's I came up against almost no one could out muscle him. Defending-wise Barkley is a bit shaky with any sliding challenges but is perfectly competent in standing tackles and rarely lets anything past him. despite being placed in a defensive position, Barkley managed to contribute his fair share of goals and assists as well managing to score 8 and assist 12 in just 31 division rivals matches (mixture of division 3 and 4). My only gripe about Barkley would possibly be his Stamina. I was applying a squad fitness after every second match and by the 60th minute in the second match Barkley would be extremely tired.
Passing (both long and short)
Stamina - without question
