Watford have signed Nigerian striker Ola Adeyemo after his successful trial with the Under-21 team. The forward started training with Harry Kewell’s Under-21 team in January and scored during their friendly victory over Reading. Former Dundee United striker Adeyemo, 21, went out to India with Kewell’s squad for the recent Nagjee Cup where the Hornets reached the semi-finals. Adeyemo also featured for the team in Professional Development League games against QPR and Millwall which helped secure a contract with the Under-21s. Born in England and brought up in Ireland, Adeyemo qualifies to represent Nigeria by descent and was called up to their under-23 team in January 2015.
