Everton boss David Moyes is already in talks over a permanent deal for on-loan Manchester City striker Jo.
Moyes has the Brazilian striker on loan and his impact was stunning with two goals on his debut against Bolton.
Moyes tried to buy Jo, 21, last summer but was priced out by CSKA Moscow's £18m valuation, which City were happy to meet.
But the Eastlands club may accept half of that figure for the striker at the end of the season after just one goal in nine starts for City.
