Brighton have completed the permanent signing of teenage defender Tariq Lamptey for an undisclosed fee from Chelsea.
The 19-year-old, who made his Premier League debut against Arsenal earlier this season, has agreed a three-and-a-half-year deal.
Seagulls boss Graham Potter said: “We are really pleased to have secured the signing of a really exciting young talent in Tariq.
“I am now looking forward to working with Tariq on the training pitch to help him develop further, and I’m sure our supporters are looking forward to seeing him in an Albion shirt.
“With his pace and technical ability, Tariq provides us with another option on the right side of the pitch both at right-back, where we already have good competition, and also further up the pitch.”
Lamptey was born in Hillingdon, London, and is also eligible to play for Ghana through his father Ahmed.
