Watford are looking to sign the Lille midfielder Thiago Maia before the window closes.
According to Le10Sport, the Premier League club have already submitted a €20million bid for the Brazilian defensive midfielder.
Even if Lille accept the offer, it will be interesting to see if they can convince the player to join now.
The report from Le10Sport adds that the French outfit are holding out for a fee of around €25million.
Maia was linked with a move to Newcastle United earlier this summer and the player prefers to join them over Watford.
