The Nigerian defender also had undertaken a trial with Norwich prior to his move to the Emirates Stadium but declined the offer of a six-month deal in order to pursue other potential moves.
The 19-year-old defender scored on his debut for the under-21s in a 3-0 victory over Blackburn Rovers, before putting in another accomplished display for Steve Gatting’s side in a 1-0 win over West Bromwich Albion at Emirates Stadium earlier in September.
Ajayi blew the lid on the proposed move last week after tweeting that he had signed a contract with the Gunners. He said:
Delighted to announce that I have officially signed for Arsenal. Can’t wait to see what the next two seasons here have in store for me.
It was sad to end my ten year spell with Charlton this summer but I can’t speak highly enough of all of the wonderful people I met during my ten years there and I wish all those at Charlton the best for the future as I will always have a soft spot for the club and its fans.
Ajayi has represented Nigeria at under-20 level three times but is still eligible to play for England, having been born in London. The club has now officially confirmed the signing on official website. It stated:
Everyone at Arsenal would like to welcome Semi to the Club.
Ajayi spent a spell on loan with non-league Dartford last season, where he made three appearances, and his move to Arsenal represents a rapid rise having never played in the league for Charlton. The player underwent a trial period with Arsenal last month before the club took the decision to offer him a permanent deal, and Ajayi becomes the second player to join from Charlton after Jenkinson.
At 6 ft 3 in, he cuts the figure of an imposing center back and, after coming through the ranks at Charlton, will help to add steel to Arsenal’s under-21 side. He might not make an immediate impact on Arsenal’s first team but he is the one for the future and is a typical Wenger signing. The lad is reportedly very good and it will be interesting to see how much of a future he has here.
We welcome Semi to the Emirates and wish him to have a successful reign with the club.
