Leeds United may not be able to complete the signing of Jack Harrison until the end of August, Football Insider understands.

The Yorkshire giants were hoping to trigger the option in the Man City winger’s loan contract and sign him as soon as the window opened in June.

A league source has told Football Insider that the Football Association may now not allow the transfer window to open until after the season has finished, which would be following the Champions League final.

Uefa is now working to plans that would see final end the 2019-20 season on 29 August.

The window would then potentially open for business, although it is unclear when the it would close.

FIFA have already told individual national associations they can schedule the transfer window when it suits them.

This would push back Leeds’ plans to formally register Harrison as their own player.

United have made provisions for the former England Under-21 international to join full-time, with a permanent option included in his loan contract.

Details of the clause, which can be triggered at the end of this campaign, were first revealed by Football Insider shortly after last summer’s transfer window had shut.

The stipulated fee is set at just below £10million for Harrison, whose City deal runs until the summer of 2022.

Marcelo Bielsa has showed immense faith in the young attacker during his reign and is in no doubt he has the capabilities of being a potent Premier League performer in the future.

At Leeds, he has remarkably started all 37 of their Championship games this season, scoring five goals as well as supplying seven assists.
