Arsenal and Man United are interested in Matheus Fernandes but West Ham have been warned to lower their asking price.The Hammers want in excess of £80million and it’s expected the Portuguese midfielder will push for a move from the London Stadium following the club’s relegation.West Ham were relegated on the final day of the season despite beating Leeds 3-0GettyDespite a disappointing campaign for the Irons, the 21-year-old impressed individually, scoring five goals and providing five assists in the Premier League. West Ham’s high valuation stems from the inflated market that brought Fernandes to east London in the first place.Having signed from Southampton, his original move to the capital already comfortably sits among the top five most expensive transfers from a Championship club.They paid £38m, plus £4m in add-ons, to the Saints just 12 months ago.Nuno Espirito Santo would prefer to keep Fernandes, yet the board may be forced to sell the youngster due to their lack of Premier League revenue from next season.Crucially, whatever transfer fee the Hammers secure for the playmaker, they will owe Southampton a 15 per cent cut due to a sell-on clause written into his previous contract.West Ham are seeking double the fee they paid for Fernandes.Arsenal prioritiesDespite the player’s obvious quality, Jeff Stelling insisted on talkSPORT Breakfast that the club’s relegation completely destroys any leverage they think they have in the transfer market.He said: “My immediate thoughts are £80m in West Ham’s dreams because they’re in such a financial situation that they can’t bargain up big time, I’m thinking maybe £50m.”“I like him a lot as a player, but he is not a priority for Arsenal.”Ally McCoist responded: “I think he’s an excellent player, and I think he certainly can play at a real top level, elite level.“But if you’re asking me where Arsenal’s priorities lie, left-hand side and centre-forward attack. Concentrate there.Man United are among multiple clubs keen on FernandesGetty“Your midfield’s good with Zubimendi coming on for Lewis-Skelly.”Stelling added: “I think it’s a ridiculous price. He’s not going to cost that sort of amount of money.“Frankly, if he goes there, as much as I like him, he wouldn’t be a guaranteed starter.”The World Cup factorAdding fuel to the transfer fire is the 21-year-olds recent international heartbreak, having been left out of Portugal’s squad for the upcoming World Cup.In order to force himself back into Roberto Martinez‘s fold, the midfielder needs a high-profile move out of the Championship to a top-tier club.Relegated clubs face a massive drop in revenue after falling to the second division and Arsenal won’t be fooled by the Hammers’ situation, knowing the east London-outfit will have to balance their books.Rogers scored 13 goals and provided 11 assists across all competitions for Aston Villa this seasonGettyArsenal are also linked with alternative options for the same role, including Aston Villa’s Morgan Rogers after he helped the midlands clubs secure their first European trophy in 30 years.The potential arrival of either the England international or Fernandes would raise doubts over the long-term futures of Gabriel Martinelli and Leandro Trossard, as Mikel Arteta looks to evolve his squad for next season’s title defense.
