Everton midfielder Idrissa Gueye is a player who Marco Silva is desperate to keep at Goodison Park.
According to the Daily Mirror, Everton boss Marco Silva is upset with Idrissa Gueye.
Gueye has reportedly decided that he would like to leave Goodison Park to join Paris Saint-Germain, after interest from the French champions.
Everton are determined to keep hold of Gueye, even though PSG have made a £25 million offer for the defensive midfielder, as Silva thinks he would be impossible to replace this month.
And the Everton boss is said to be disappointed that Gueye is keen on a move to PSG.
Silva wants to keep Gueye in his Everton team for the years ahead, and has shown great faith in the midfielder so far this term.
Everton are believed to effectively be ruling out all sales of Gueye, who is on a £75,000-a-week contract (Goal), unless a mammoth bid comes in from PSG.
The Toffees would like to raise funds for a striker, but the sale of Gueye will only be sanctioned if the offer becomes too good to refuse.
