Rubin Kazan have made a £15.4m offer to Celtic for forward Odsonne Edouard, while Everton have also shown an interest in signing the striker.
The Russian club are proposing to pay the fee in three instalments over 12 months with the first payment around £8.5m followed by two blocks of approximately £3.4m.
Everton have sounded out a deal to bring the forward to Goodison Park, with manager Rafael Benitez also keen on Brighton’s Neal Maupay although the Toffees are in a position where they must sell to buy as the club remain hamstrung by Financial Fair Play rules.
Bordeaux are also willing to match Rubin Kazan’s bid for the French striker.
Leicester also held talks over the in-demand striker in June with Brendan Rodgers a keen admirer of Edouard, having signed him as Celtic boss in 2017 on an initial loan deal from Toulouse before the club acquired him on a permanent deal for a club-record £9.3m from Paris Saint-Germain a year later.
Reports claim Edouard is prepared to let his contract expire, leaving him free to speak to other sides in January.
