Everton will place a 'prohibitive valuation' on Iliman Ndiaye after Manchester United expressed interest in signing the midfielder. The Toffees want around 80m euros for the Senegalese winger, who has made 71 appearances for the club over the past two seasons, scoring 15 Premier League goals. Ndiaye is contracted to Everton for another three years but the club are keen to tie him down to an even longer and more lucrative deal. According to The Athletic, the point of contention is the presence of an exit clause that could be triggered as early as this summer. Everton boss David Moyes is desperate to keep hold of Ndiaye, who has rejected multiple contract offers over the past 12 months. Moyes branded Ndiaye the 'last person I would consider selling' when asked about speculation he could leave Everton. Manchester United are set to make Brazilian midfielder Ederson their first signing of the Carrick era after agreeing a £35m deal with Atalanta. The Red Devils are expected to bring at least one more central midfielder to the club amid interest in Elliot Anderson, Adam Wharton, Sandro Tonali and Carlos Baleba. United are also keen to sign a new left-back to support Luke Shaw and another striker to provide competition for talented but inexperienced Benjamin Sesko.
