Chelsea have signed Spain international full-back Marc Cucurella from Brighton for about £50m.
The defender, 24, handed in a transfer request after interest from Manchester City, but they did not pursue a deal and deemed the fee too high.
Cucurella was with Brighton for just one season after joining from Getafe, making 35 appearances and scoring once.
He becomes Chelsea's third summer signing after forward Raheem Sterling and defender Kalidou Koulibaly.
The Blues have also agreed a £20m fee with Aston Villa for teenage England youth international Carney Chukwuemeka.
Last month, the Seagulls rejected a £30m bid from champions City for Cucurella and saw £50m as the benchmark - the fee Arsenal paid for England defender Ben White last summer.
