Everton, West Bromwich Albion, Crystal Palace and Middlesbrough all scouted KAS Eupen striker Henry Onyekuru this week, sources close to the player have told ESPN FC.
Onyekuru is a target for a number of Premier League clubs this summer after impressing for Belgian Jupiler League side Eupen this season.
The attacker scored his 22nd goal of the campaign in front of scouts from the four English clubs in Wednesday's 2-0 win against Mouscron to make him the top scorer in Belgium. He has scored eight goals in his last nine games in the Belgian Jupiler League playoffs.
Scottish champions Celtic saw a bid for the 19-year-old rejected during the January transfer window and they have continued to keep tabs on the player.
However, Onyekuru is keen to win a move to the Premier League and his suitors have been alerted to the £6.8 million release clause in his contract, with Eupen resigned to losing their prized asset this summer.
