Watford are reportedly concerned that their deal to sign Tottenham Hotspur midfielder Benjamin Stambouli will collapse.
The newly-promoted Premier League outfit are rumoured to be closing in on a £4m swoop for the 24-year-old.
However, according to the London Evening Standard, Stambouli is yet to sign the contract offered to him, which has sparked fears among the Watford camp that the midfielder is considering pulling out of the move.
Stambouli joined Spurs from Montpellier last year.
