If it’s about money – it’s usually the Premier League’s fault.
Despite Sevilla tying up a deal to sign Luis Muriel from Sampdoria, the Spanish club are paying more than they would have wanted. Spanish newspaper Marca report that Everton and West Ham were both interested in the forward, and made the transfer more expensive than it needed to be.
West Ham were the club mainly linked with Muriel with claims in both the Italian and English media of offers being pending, Everton were linked because of the assumption they needed to add more upfront given what was then a likely transfer of Romelu Lukaku.
There’s a distinct possibility that neither Everton or West Ham were actually seriously interested, in which case it’s the media who would have upped the player’s price rather than the clubs.
