Manchester United are locked in a heavily-contested battle with Tottenham Hotspur to secure the signature of West Ham midfielder Mateus Fernandes.
The 21-year-old Portuguese international has emerged as one of the most coveted young talents in the summer transfer window following the Hammers’ relegation from the top flight last season.
Senior officials at the London Stadium have placed an £85m valuation on their prize asset, refusing to budge on their demands despite dropping down to the Championship.
July 1 marks the beginning of the new financial year for football clubs and is expected to spark the market into life with formal opening bids.
Tottenham are understood to be willing to meet the steep asking price and could offer more lucrative personal terms to the player, but their successive 17th-place finishes in the Premier League could hinder their pursuit.
Conversely, Manchester United can offer the massive allure of Champions League football after finishing third under Michael Carrick.
Having already agreed a £35m deal with Atalanta to sign Brazilian midfielder Ederson, the Red Devils view Fernandes as the ideal technical addition to complete a comprehensive summer engine room overhaul.
If both clubs ultimately submit matching financial proposals to West Ham, the final decision will rest entirely with Fernandes, who must weigh up the wage packets on offer in north London against the sporting prestige of moving to Old Trafford.
