West Ham have signed Waterford United’s teenage striker Seán Maguire after he impressed on a trial with the London Premier League club.

The 18-year-old scored 13 goals in Waterford’s Airtricity League First Division campaign last season, helping them finish in second place before they lost the promotion/relegation play-off over two legs to Dundalk.

Maguire joined Waterford from Kilkenny junior club Evergreen, where he enjoyed a prolific scoring record, including over 50 goals in his final season at the club.

His form last season earned him a nomination for PFAI young player of the year, an award won by Chris Forrester of St Patrick’s Athletic.
