Arsenal have rejected a £30m offer from Everton for Alex Iwobi, but the Toffees are expected to return with an improved bid.
The offer is believed to have been an initial £25m fee, with a further £5m in performance-related add-ons.
The Gunners have turned down the deal, but the Merseyside club are expected to return with a second bid for the 23-year-old Nigeria international.
Iwobi will have plenty of competition for a place in Unai Emery's starting XI this season, with new club-record signing Nicolas Pepe, Henrikh Mkhitaryan, Reiss Nelson and even Pierre-Emerick Aubameyang vying for a spot out wide.
Everton have just over 24 hours to complete the deal, with the summer transfer window slamming shut at 5pm on Thursday.
