The 20-year-old has just been promoted to Metz’s senior squad and is waiting to sign his first professional contract.
But in recent days, the three English clubs have approached the Franco-Moroccan shot-stopper.
Watford proposed a straight three-year deal to Gourari Tebaa with a wage offer that seemed to suit him.
Everton have also come forward but they want to initially place him in their under-23 side.
And Brighton have also expressed an interest but have not yet made a concrete offer.
In addition, Turkish Süper Lig sides Trabzonspor and Antalyaspor have spoken to Gourari Tebaa’s camp, but again without making any offers.
For the moment, Gourari Tebaa’s priority is to stay with Metz and succeed there, but the situation could change.
The talented goalkeeper is eligible to play for France, Morocco or Algeria at international level.
But earlier this year, Gourari Tebaa confirmed he had chosen to represent Morocco.
