Done deal: Youngster leaves

Armstrong Oko-Flex has left West Ham to join Swansea on loan, the lower-league club have confirmed.

The 20-year-old is set to spend the rest of the season with the Welsh club as he bids to play first-team football.

Russell Martin has completed the signing of the former Celtic winger, and he could make his debut in the clash with Stoke City on Wednesday.

Oko-Flex recently made his first-team debut for the Irons against Viborg in the Europa Conference League playoff but he was mainly restricted to appearances at youth level last season.

A Republic of Ireland youth international, he made 27 appearances in total for the Under-21s and scored 13 goals, while also laying on two assists.

He also made two senior appearances for Celtic and he will now hope to play regularly for Swansea as they bid to win promotion from the Championship and climb into the Premier League.

Oko-Flex can play as a left winger and as a central striker.
