Bournemouth manager Eddie Howe
Mousset, 21, has emerged as one of the top young prospects in French football over the last year, having enjoyed a superb season with Le Havre.
The forward, who can play up front or out wide, hit 14 goals in 29 games last term, with only 16 appearances coming as starts - and his exploits appear to have triggered major interest in his signature.
L'Equipe report that, whilst there are some issues to be sorted out in the deal, Mousset is expected to become a Bournemouth player by the end of the week, as manager Eddie Howe adds more attacking firepower to his ranks at the Vitality Stadium.
The report highlights just how much of a coup this is for Bournemouth, as L'Equipe claim that four Premier League rivals were looking at making moves for Mousset this summer too.
Arsenal, Southampton, Sunderland and Tottenham Hotspur are named as teams who were keen on Mousset, but it's Bournemouth who appear to have won the race for the striker's signature.
Both Arsenal and Spurs are in the market for attacking options this summer, and 20-year-old Mousset could have been seen as one for the future for managers Arsene Wenger and Mauricio Pochettino.
Meanwhile, Sunderland are likely to look to the French market again this summer after Lamine Kone and Wahbi Khazri impressed last season, and with Jermain Defoe needing support in attack, Mousset could have fit the bill for Sam Allardyce.
Sevilla, CSKA Moscow, FC Copenhagen, Bristol City and Monaco are also credited with an interest in Mousset, and reports from the Bournemouth Echo last week suggested that the Cherries will be paying around £7m to land the pacey forward in a major deal for Howe's men.
Do you think Mousset will be a success for Bournemouth?
