Nathan Tella has left Arsenal for Southampton
Tella, 17, has been at Arsenal for 10 years but was out of contract at the end of the season.
He was told he won't be given a new deal and has been free to look for other clubs.
Tella, a boyhood Gunners fan, was invited to train with Norwich but ended up on trial at Southampton.
And he's impressed enough to be handed a contract with the Saints.

Nathan Tella has agreed a move to Southampton
The St Mary's outfit are famed for their strong youth system and Tella says he's signed "to start a new chapter".
The winger said: “I am delighted to have signed here.
“It’s just a relief to know that I have found a place that I can settle down and crack on with my future.
“I had a really good ten years at Arsenal and I wouldn’t change any of it, but I am looking forward to starting a new chapter here now.”
Tella will now complete the remainder of his scholarship with Saints and will be with the club until the end of the season.
