Sporting CP striker Viktor Gyökeres is reportedly “furious” that the Portuguese champions are complicating his summer exit.

Manchester United have taken the first step in their attempts to strike a deal for Viktor Gyokeres this summer. The club have already been active in the transfer market, signing Matheus Cunha from Wolves for a fee of £62.5million. United are also working on a deal to bring the Brentford's Bryan Mbeumo to Old Trafford.

Record report however Sporting president Frederico Varandas has decided not to honour that agreement. While the Portuguese champions are still waiting for official bids, clubs who have made enquiries have been told it will cost at least €80m to do business.
