Sime Vrsaljko says he would prefer to join Atletico Madrid over Napoli and is "optimistic" a deal will be completed this summer.

Vrsaljko is currently with Sassuolo and Atleti is prepared to pay around €15 million.

Vrsaljko would give Atleti another option at full back.

"Right from the first moment that this possibility started to take shape, I told the Sassuolo management that Atletico Madrid was the only club I wanted to join," said Vrsaljko.

"I also told them I don't want to go to Napoli even though a transfer was all agreed."

He added: "I can say, at least for what I know, that Atletico and Sassuolo should close the deal," he said. "I am optimistic."
