Watford youngster Kamil Conteh will join Middlesbrough this summer once his contract expires.

The midfielder made his senior debut earlier this season in the FA Cup defeat away at Leicester City, and was also included in the matchday squad for the home defeat to West Ham, but was kept on the bench.

The 19-year-old has had trials with Boro as recently as last month, featuring in an Under-23’s match against Nottingham Forest.

He will depart at the end of next month, with his current deal running until June 30.
