Chelsea have reportedly submitted a £17m bid for Metz forward Habib Diallo.
The Blues, having had their transfer suspension lifted, are able to enter the market in January and continue to be linked with a number of players in the final third of the field.
According to Le Republicain Lorrain, Frank Lampard's side have made an offer of £17m for Diallo, who is also believed to be attracting the attention of Leicester City and Tottenham Hotspur.
The 24-year-old has scored 10 times in 19 Ligue 1 appearances for his French club this season, while he managed 26 in the second tier of French football during the 2019-20 campaign.
Diallo will see his current deal with Les Grenats expire in the summer of 2022.
