Forward Nickson Okosun will join Watford from Irish club Bohemians in January for an undisclosed fee.

He has signed a contract that commits him to the Hornets until 2029, and will initially become part of the club’s Under-21 team.

He has been given permission to train for the rest of 2024 with Watford, who have the option to extend his contract by a further year.

The Ireland Under-19 international progressed right through the Bohs academy system to the first team having originally joined from fellow Dublin-based club St Kevin's.

Okosun helped Bohemians win the Under-17 league in 2021 and the Enda McGuill Under-19 Cup in 2022.

He earned his first professional contract with the club in January 2023.

The forward can play through the middle or on either flank, and made eight first-team appearances for Bohs during the 2024 season which finished last month.

He only started once, against Malahide in the Leinster Senior Cup, and has played a total of 172 minutes of senior football.

In March 2023, Okosun scored the winning goal for Ireland’s Under-17s in a 3-2 win over Cyprus, which booked their place at that summer’s UEFA European Under-17 Championship in Hungary.

The forward went on to play in the tournament, where his country reached the quarter-finals.

“I’m happy to be here and I can’t wait to get going,” Okosun told watfordfc.com.

“I like to link up and get in behind, and I love scoring goals as well.

“It’s a big club and there are good people, and Watford really resonated with me in that sense.

“Hopefully, I’ll hit the ground running and I’ll try and impress people here.”

Okosun’s former club Bohemians finished eighth in the 10-team League of Ireland Premier Division.

They are the oldest League of Ireland club in continuous existence, playing their home games at the 4,500-capacity Dalymount Park in Phibsborough on the north side of Dublin.

Bohs have won the League of Ireland 11 times, and lifted the FAI Cup seven times.

Other players who have left Bohemians and forged a career in England include Stephen Ward, Matt Doherty and Ashley Grimes.
