It is a week since the transfer deadline passed, and at French side Marseille, the shock waves are still being felt after a frenetic window.
The Ligue 1 side saw 22 players depart, and 16 sign, which included Abou Diaby and Remy Cabella.
A report in French newspaper La Provence, re-published online by But! Football Club claim that Marseille could have let a 23rd player leave, after a big offer came in for striker Michy Batshuayi.
The mystery bidder is not disclosed, but the fee is quoted at £22 million, and 'likely' to have been an approach from a Premier League team.
Marseille had already lost last season's top goalscorer Andre-Pierre Gignac, and so were particularly determined to keep Batshuayi, considering the players they had already sold this summer - key men Dmitri Payet, Florian Thauvin and Giannelli Imbula but to name a few.

Tottenham were also confirmed to be in negotiations with Marseille over the transfer of Erik Lamela, as reported Le Parisien, only to change their minds at the last minute. It is not a stretch to think Batshuayi's name could have come up in negotiations.
The possibility of Aston Villa being the mystery bidders is plausible but far more circumstantial. Villa had money to spend after cashing in on Christian Benteke, and signing one of his stand-ins for the Belgian national team could have been a smart move.
Villa also invested in the French market this summer, buying Jordan Ayew, Jordan Veretout and Jordan Amavi all from Ligue 1 sides, and Batshuayi could well have been on their radar.
