Leeds United boss Simon Grayson says he will not prevent Peter Sweeney from returning to Grimsby Town.
Sweeney finished last season on loan at Blundell Park and Mariners manager Mike Newell wants to sign the midfielder permanently.
A deal has yet to be agreed between the two clubs, but Grayson is prepared to allow Sweeney to leave Elland Road over the summer.
Grayson said: "Peter hadn't figured in the team at all under my management, so it was an opportunity for him to go to Grimsby and get some games last season.
"He impressed there, so there is probably a good opportunity to make the move permanent. We won't stand in his way."
Meanwhile, Newell insists he is not concerned by the lack of new arrivals at the League Two club ahead of the start of pre-season training.
Newell told the club's official website: "The players are back on Monday, but there is no rush to bring players in yet.
"Sometimes it takes longer than you would like, but we won't be pressured into signing players that we don't really want.
"Pre-season is about getting fit and I've never worried about results pre-season."
