West Ham hope to conclude the signing of Henry Onyekuru this week after convincing the young Nigerian to snub Arsenal.
Talks are ongoing with his club Eupen over the fee which will be intrinsically linked to the 20-year-old gaining his work permit.
However, Onyekuru has been convinced by West Ham that a move to the London Stadium would be of greater benefit to his career and will offer him the platform to play regularly in the Premier League.
He is expected to fly to London on Tuesday ahead of a prospective medical if talks continue to progress well.
