Tottenham's England full-back Kieran Trippier has completed a move to Atletico Madrid, the Spanish club confirmed on Wednesday.
Trippier, 28, put pen to paper on a three-year deal at the Wanda Metropolitana.
Atletico paid out £20 million ($25m) for the player, a fee that could rise in the future due to add-ons and bonuses negotiated between the two clubs.
The Colchoneros have invested heavily in shoring up their defence so far in the summer transfer window.
With stalwart centre-back Diego Godin leaving for Inter, Atleti swooped for Porto's Felipe as a replacement for the Uruguayan.
