Brighton have made an £18.5m bid for Celtic striker Odsonne Edouard in a deal that could potentially break the £20m mark in the future.
The 23-year-old is in the final year of his contract in Glasgow, meaning the Hoops could be forced to sell their star striker this summer or face losing him for nothing at the end of the season.
And the Daily Record reports that Celtic have indeed received an £18.5m offer from Brighton for Edouard, which includes a series of add-ons and potential future bonuses, depending on what the Frenchman goes on to achieve.
The £18.5m sum will stand as a concrete initial fee, but the Seagulls have also included performance-related bonuses which come to a total of an additional £3.5m. On top of that figure - which would send the transfer over the £20m mark - a sell-on clause worth between five and 15% has also been offered, should Brighton receive a bid north of £30m for Edouard in the future.
Celtic are aware that they have little room to negotiate this summer, with Edouard's contract set to expire in 2022 and little sign of a new deal on the horizon. The Scottish giants know they may have to cash in while they still can, as they do not want to lose their hitman for free in 12 months time.
Meanwhile, Brighton are desperate to boost their attacking options after suffering a frustrating season in front of goal. Despite creating plenty of opportunities and often winning matches on 'xG' (expected goals), the Seagulls failed to put away their chances and dropped far too many points.
The arrival of Edouard means they'd possess a proven goalscorer, having bagged 21 and 16 league goals in his last two seasons at Celtic Park respectively. The forward has even worked his way into France's Under-21 setup, and is highly rated around Europe.
It would certainly prove to be a major coup for Graham Potter and Brighton if they were able to lure Edouard to the south coast.
