Lyon will reportedly cash-in on Moussa Dembele this summer after failing to qualify for European football next term.
And the asking price has offered a major clue as to how much Celtic could land with a sell-on clause built into his deal.
Dembele continued to shine for Lyon despite his club underperforming in Ligue 1 finishing in eight spot and well adrift of the Champions League and Europa League spots.
The striker netted 13 goals in 11 league games to round off the season and has caught the eye of suitors in the English Premier League.
Foot Mercato report that Arsenal and Tottenham are monitoring his situation this summer as they look for reinforcements up front.
It is also noted in The Daily Mail that Dembele would count as a homegrown player for an English Premier League side having come through the youth ranks at Fulham.
It is claimed that Lyon would willing to let their captain leave the Groupama Stadium for a £25million fee.
When Dembele left Parkhead for France in 2018 for £19.7million, a 15 per cent sell on clause was inserted into the contract.
If a £25million move is completed that would see Celtic pocked an additional £3.75million.
That would offer a welcome boost to the club as Ange Postecoglou prepares his squad for a return to the Champions League group stage.
