Probably won't see any new loan signings until the season starts and DA has had a chance to assess what is needed and what is available, also parent clubs will want the loanee to have had a full pre-season with them.29.06.2017
I think the only limit enforced by EFL is a maximum of 5 can be included in the match day squad, the reason they get loaned is so the player can get match experience, so no point signing more than that.
