Former Arsenal youth product Tyrell Robinson is on trial at Vicarage Road, two months after he was released by the Gunners.

The 19-year-old defender was an un-named trialist in a number of the Hornets' recent Under-23 games, and has netted in their games against Nottingham Forest and Bolton.

Robinson is a left-winger by trade, but spent much of his time with Arsenal deployed in defence, a move which hastened his departure from the Emirates Stadium.

He already held trials with QPR, West Ham and West Brom earlier this season.
