Is Le Bris' squad planning sensible?

Former Sunderland forward Marco Gabbdiani has been speaking about Sunderland's transfer strategy this summer and Regis Le Bris' desire to have a "core squad" of around 20 players.

"Some of it comes down to logistical planning for numbers in training sessions. It's very difficult to put sessions on for 24, 26 players. It's almost impossible." Gabbiadini told BBC Radio Newcastle.
