Leeds United have mitigated the cost of their £15million signing of Helder Costa by spreading the payments to Wolves across four years, Football Insider understands.

The Portugese winger moved to Elland Road last summer when it was announced he had signed on an initial season-long loan that would eventually become a full-time transfer.

A Leeds source has told Football Insider that Costa will be handed a four-year contract starting on 1 July and the transfer fee will also be paid in instalments.

It is not uncommon for transfers to be spread across a number of payments, and different accounting periods.

Leeds are set to pay for Costa across four years, running to the end of his contract in 2024.

That reduces their annual costs and avoids the possibility of them having to stump up £15m for him as a Championship club if they failed to get promoted and on board the Premier League gravy train next season.

Marcelo Bielsa’s side have already paid an initial multi-million loan fee to Wolves to take Costa for this season.

By contrast, permanent deals for Leeds’ other loan stars Jean-Kevin Augustin, Jack Harrison, Ben White and Illan Meslier are up in the air.

They are dependent upon various factors, including promotion and negotiations involving the parent clubs and the players themselves.

Costa has been a mainstay of the team after struggling to break into Bielsa’s XI at the start of the campaign.

The Portugal international has made 27 Championship starts among 40 appearances in all competitions, scoring four goals and supplying five assists.
