I have to agree with Romey regarding the squad having the same amount of depth as last year; however, the squad is deeper compared to three seasons ago.
I still think we need another winger(left-footed) and a younger CB to cover Distin with the intentions of eventually taking over for him. Obviously, another striker is preferable to challenge Lukaku, but I feel that way because of the question marks hanging over Kone's head. I also wouldn't mind acquiring another central attacking playmaker to challenge Barkley. I feel Pienaar could do a job there, but I have a feeling he's not going to get that opportunity very often.
