Arturo Vidal: Inter Milan sign midfielder from Barcelona

Conte will be hoping the trio's experience can help Inter win trophies this season after they finished as runners-up in both Serie A and the Europa League during the previous campaign.

Vidal's exit from Barcelona comes as the Spanish side look to rebuild following their first season without a trophy in 12 years.

Arthur, Ivan Rakitic and Arda Turan have already left the Nou Camp, while youngsters Carles Perez and Marc Cucurella have been sold. Luis Suarez is also set to join La Liga rivals Atletico Madrid.

However, captain Lionel Messi is staying at Barcelona after reversing his decision to leave, and he paid tribute to Vidal in a post on Instagram on Sunday.

He said: "I only knew you from playing against you and I always thought you were a phenomenon, but after being lucky enough to get to know you personally you surprised me even more.

"We shared many things in the last two years and you made a huge impact on the dressing room and will be dearly missed. I wish you all the best luck in your new club and I'm sure our paths will cross again."
