Charlton Athletic have signed former Arsenal trainee Zak Ansah.

The 20-year-old forward, who came through the youth ranks with the Gunners, has put pen to paper on a two-year deal following his release by the Barclays Premier League club.

"When a player of his calibre becomes available you can't ignore it," development squad coach Jason Euell told the Addicks' official website.

"I have a good relationship with his dad [former Southend United midfielder Andy Ansah] so I know what he's about and what sort of a player he is and with him being a local lad we wanted to get him in as quickly as possible."

"We've looked at what Zak brings to us as a player and he fits in with how the club want to move forward.

"He'll be 21 come the end of the season and he's the sort of player that, we hope, can make a difference to our first-team."

Ansah impressed at all levels as he progressed through Arsenal's academy and was rewarded with a place on the bench during a Champions League tie at Olympiakos in December 2012.

He has represented England at Under-16 and Under-17 level and was called up for Ghana Under-20 squad as they prepared for last year's FIFA Under-20 World Cup in Turkey.
