Charlton have completed the signing of David Button from Tottenham, offering the goalkeeper a fixed abode following an impressive number of loan deals.
The 23-year-old is a product of the White Hart Lane academy system, but has never come close to forcing himself into first-team reckoning.
Spurs have, however, been keen to further his development away from North London in the hope of moulding him into a senior star.
They have succeeded in their efforts, but have allowed Button to open a new chapter in his career at a capital rival.
Charlton have succeeded in snapping him up on a two-year contract for an undisclosed fee.
Button will now be hoping to put down roots at The Valley after taking in 13 loan spells in four years.
"I'm delighted," the promising shot-stopper told the Addicks' official website.
"It's a massive opportunity for me to come to a massive club like this and I'm really excited for the future."
Charlton boss Chris Powell added: "We are really happy to bring David to the club.
"He's someone we've been monitoring for quite some time and is a hugely talented young keeper who is a good age and boasts all the right attributes.
"He's come through the ranks at Tottenham and also has played youth football internationally as well as playing for quite a few clubs on loan, including in the Championship.
"This represents a new chapter for him and it's great that he feels it's the right time to make this move and further develop here at The Valley.
"David will provide strong competition in the goalkeeping department and that can only benefit us going forward."
