One of the major issues with Chelsea's squad in recent months has undoubtedly been the size of it. Frank Lampard identified the issue as one of his struggles while in charge of the club. While the numbers in the squad were unwieldy, with players left out of the Blues' Champions League squad, other issues emerged too.
He noted in his final press conference: "The squad has been too deep and that's the biggest challenge I've found day to day. Coming in and trying to work with big numbers and players that are maybe a little bit, for whatever reason, disillusioned, for right or wrong, that they're not playing or they might be leaving."
The challenge and opportunity this summer was laid out by Lampard: "We will have the capability as a club and for the new manager to get the squad in the place he wants it to be. That's going to be some work as well".
