Jerome Sinclair is set to join Watford in the summer after the paperwork on the deal was finalised, Football Insider sources understand.

The Hornets failed with a bid to tempt the Merseysiders into selling the teenage forward in the January window.

But the Premier League club have continued to pursue the 19-year-old and have made a breakthrough in their bid to entice him to Vicarage Road.

A source close to the situation has told Football Insider that Sinclair has agreed in principle to sign a three-year Watford contract with the option of a fourth year.

His Liverpool deal expires on 30 June and he will then complete the formalities of a move to Watford, although an announcement is expected imminently.

Sinclair has decided to move after failing to to break into the first team under Jurgen Klopp and his predecessor Brendan Rodgers, and has made only one start for the Reds.

Liverpool will be due a compensation fee from Watford due to the youngster’s home-grown status. Sinclair moved to Anfield as a 15-year-old from West Brom in 2011.

Football Insider revealed in March that Sinclair was in advanced talks to join Watford after being offered a contract by the club.

The teenage striker has rebuffed attempts from the Merseysiders to extend his deal.

Liverpool had placed a £2million valuation on the striker in January but, even though he is out of contract in the summer, the club are in line for a compensation fee under FA rules as the player is aged under 23.

In total, Sinclair has made five appearances for the first team and scored just the one goal, in the FA Cup third-round 2-2 draw against Exeter in January.

In other Liverpool transfer news, one of the starters at West Brom last Sunday will be allowed to leave the club this summer after failing to impress Klopp.
