Leeds sign full-back Junior Firpo for about £13m.
The 24-year old made 41 appearances for Barcelona since his arrival from Real Betis in 2019.
He joins Leeds on a four-year contract and Barcelona has included a 20% sell-on clause in the deal.
A statement in Leed’s official website read: “The Whites have beaten off competition from a number of clubs to secure the services of the 24-year-old, who joins from Spanish outfit FC Barcelona for an undisclosed fee.
“Following a period of quarantine and completion of his medical, the full-back signed a four-year deal at Elland Road, running until the summer of 2025.
“Born in the Dominican Republic, Firpo moved to Spain at a young age and made his breakthrough at Real Betis.
“Catching the eye during the 2018-19 campaign, with five assists and three goals in his 29 appearances for Betis, Firpo was called into the Spain Under-21 squad and helped them win the 2019 UEFA European Under-21 Championship.
“Following the tournament, in August 2019, he was snapped up by Barcelona, signing a five-year deal at the Nou Camp.
“Over the past two seasons, he turned out 41 times for Barcelona, helping them win the Copa Del Rey.
“Firpo becomes Leeds’ third signing of the summer transfer window and will wear the number three shirt during his time at Elland Road.”
