Ilias Chair and Mbaye Diagne have been added to Watford's list of potential summer transfer targets, as they look to strengthen their squad ahead of a return to the Premier League.

The Watford Observer understands that Chair has impressed the club and could be seen as a player they can take with them from the Championship into the top flight, although it is understood that QPR are not interested in selling the player and a formal approach is yet to be made. 

Meanwhile Diagne's loan move at West Bromwich Albion ended in relegation to the second tier this weekend, so the 29-year-old could be available this summer. 

The Senegalese striker added firepower to Sam Allardyce's struggling side in the second half of the season, scoring three times in the Premier League, while also providing two assists.

The pair are seen as options, but not definitive ones, with attacking players high up on a list of priorities for the summer and talks also held with Chelsea striker Ike Ugbo.

Elsewhere, Ashley Young's future remains uncertain, with sources close to the player suggesting that it is 50/50 whether or not he will sign a new deal with Inter.

Conversations have taken place with the full-back's representatives about the possibility of a transfer, while Young himself has said he would be open to the idea. Watford captain Troy Deeney has also voiced his support for the move.

While the club are weighing up a number of options, Colombian striker Borre is understood not to be one of them.

Reports emerged over the weekend that a move for the current River Plate forward, who would be available on a free this summer, is being considered, but club sources have since played down the link.
