Everton don't want a major loss on the 28-year-old striker it seems.
Rumours of a potential Everton exit for Oumar Niasse are gathering pace.
Crystal Palace are also reportedly interested in the Everton attacker and now it appears as if a price-tag has been set.
The report adds that Everton are only interested in a permanent sale rather than a loan.
The Merseyside club's Director of Football Marcel Brands claimed at their AGM last week that players must leave before any are signed.
The Roberto Martinez-signed Niasse, a £13.5 million addition from Lokomotiv Moscow [Irish Independent], has only managed eight Premier League goals in 31 appearances in total.
It's not a bad record, but it's not brilliant for a striker at a club with Everton's aspirations and if they can get £12 million then it's a great deal.
