I think this player is a mistake, for two reasons and two concerns.
The reasons are his injuries and form last year and the fact that I only seen him on the right flank which is overstacked ATM.
The concerns are the price tag is one of a starter, not a sub and he is inferior to Sandro and Cuadrado, so he comes as a sub the other concern is our I retest on more RBs and our lack of options to rest Sandro.
We bought Cuadrado, we will keep Licht next year and we are trying to keep dalves too, should he commit on our demands.
Imo, a 4 man defence won't hold much, because eventually barzagli will retire and bonuccis mistakes and lack of defensive qualities was the reason we changed to a 3-5man defence. This Douglas guy can only help in 4-2-3-1 a left option a true CAM would be better, he is not that could to change our formation for him and not nearly reliable.
