Barcelona complete the signing of Lucas Digne after agreeing €16.5m plus add-ons deal with PSG

Barcelona have confirmed the signing of Lucas Digne from Paris Saint-Germain in a deal worth €16.5m (£13.8m, $18.3m), plus add-ons that could bring the total to €20.5m. The 22-year-old defender has inked a five-year deal at the Nou Camp, becoming the club's third arrival of the summer following Samuel Umtiti and Denis Suarez.

Digne moved to PSG in the summer of 2014 from Lille in a deal worth around €15m, just weeks after he won the U20 World Cup with France. However, the defender struggled to make the impact expected in Paris due to the presence of former Barcelona left-back Maxwell in Laurent Blanc's first team. Following the signing of Layvin Kurzawa from Monaco, PSG sent Digne to Roma to give him first team football.

Digne grasped the opportunity in Serie A with both hands, making 42 appearances in all competitions and earning a spot in France's European Championship squad, where he served as back-up for Patrice Evra.

Reports in Spain suggested that Barcelona had been tracking his development at Roma and were looking to make a move and provide competition for Alba at the left side of defence – as the out-of-favour Adriano is expected to leave the club during the current window.

On Tuesday (12 July) further reports suggested Barcelona and PSG had already agreed terms on the move, and the current La Liga champs have now made the news official.

"FC Barcelona have reached an agreement with Paris Saint-Germain FC to sign the 22-year-old French player Lucas Digne for the next five seasons," the club confirmed.

"Barça have paid an initial €16.5 million euros with another four possible according to individual and team results. Digne's buy-out clause is €60m euros. Lucas Digne will arrive in Barcelona on Thursday early in the morning local time to undergo a medical and sign his contract. The official presentation of the player will follow."
