Arsenal have confirmed the signing of teenage defender Carl Jenkinson from Charlton Athletic.
The 19-year-old moves to the Emirates Stadium for an undisclosed fee to become the first signing of what is expected to be a busy summer in the transfer market for Arsene Wenger.
Jenkinson, who can operate either on the right or in the centre of defence, appeared nine times for Chalrton last season, while he is also a previous captain of the Finland under 19s.
The youngster was born in England but is eligible for Finland through his mother, and has also represented the former at youth level.
"This is a great move for Carl, and it's difficult to stand in the way of a player when a club the size of Arsenal expresses interest, particularly if, like Carl, you come from an Arsenal-supporting family," said Charlton chief executive Stephen Kavanagh after the completion of the transfer.
"I would like to thank Carl, his father and Arsenal for their professional manner in dealing with matters."
Meanwhile, Jenkinson added: "I will always be in Charlton's debt for the training they have given me since a young age. I'm grateful to the club's academy and all the coaching staff, so I'm delighted the two clubs have come to an agreement.
"I hope supporters will understand why I can't turn down such an opportunity, but Charlton will always have a place in my heart."
Elsewhere, young Gunners Benik Afobe, Chuks Aneke and Oguzhan Ozyakup have pledged their long-term futures to the club by signing new contracts.
