The Ivorian international striker is currently on loan at CSKA Moscow, where 11 goals in 13 appearances in all competitions this season have attracted plenty of interest.
His stock appears to be rising among Premier League teams and despite a rather blunt spell at Roma in the first half of 2015, his overall career goal scoring record is excellent.
The Daily Star claim Watford are the latest team to show an interest and owing to their excellent scouting network provided by the Pozzo family, Doumbia being on their wish-list is no real surprise.
The Hornets have made a successful transition to the Premier League after winning promotion from the Championship last term, picking up 16 points from their opening 12 matches.
Quique Sanchez Flores' side don’t concede too many, and this will help them beat the drop, yet they don’t score many either and further firepower up top will be welcomed at Vicarage Road.
Doumbia could be the perfect foil for the likes of Troy Deeney and Odion Ighalo and with money not really much of an issue at Watford, the striker certainly represents a realistic option.
