He has pace and power and very good ball retention skills. On the flip side, he is extremely left footed, is a poor passer and has ordinary first touch. He also looked like a "stupid" (Diaby type) player that is prone to awkward passes and runs that puts his own team in trouble and doesn't seem to deal very well with opponents pressing. Haven't seen him put in a single tackle of any note in the four to five every touch in a match videos that I've seen.
But, given his young age, he could be a decent option to bring in. But, he is not someone who'll even be close to being an improvement over either Arteta or Ramsey and he will need two to three years to reach a good level for us. A definite NO from my side if he costs big money.
