M'Baye Niang has rejected the chance to turn his loan move from AC Milan to Waford into a permanent deal in the wake of Walter Mazzarri's sacking on Wednesday, sources close to the player have told ESPN FC.

Niang joined Watford on a six-month loan deal during the January transfer window, with a view to a permanent move after Watford beat interest from other clubs to land the striker.

The France Under-21 international has made 15 appearances for Watford since his arrival from Milan and he helped the club secure their Premier League status.

Niang joined Watford on a six-month loan in January.

Niang helped Watford secure an impressive win over Arsenal at the Emirates on his debut and he scored the winning goal on his home debut against Burnley.

The 22-year-old also scored and assisted another goal in the 2-0 win over West Bromwich Albion last month and he started 14 of his 15 appearances for Mazzarri's side.

Watford were hoping to secure the highly-rated Niang on a permanent deal, but they have been unable to agree terms with the player alerting other clubs to his possible availability this summer.
