Norwich City have signed goalkeeper Vladan Kovacevic from Sporting on a four-year contract with an option for a further 12 months.

Kovacevic was most recently on loan with Polish club Legia Warsaw, and played against Chelsea in the Europa Conference League.

The Canaries have paid an undisclosed fee for the 27-year-old, who is the third keeper signed this summer after Daniel Grimshaw and Louie Moulden following the exit of first-choice Angus Gunn.

Sporting director Ben Knapper said Kovacevic is of "real pedigree" and added: "With over 250 career appearances under his belt, he comes with great experience and with the mentality to perform at a very high level.

"He's hungry to improve and develop, and those qualities are essential for us in what we are building here.

"His character is a great fit with the rest of our goalkeeping group, providing an atmosphere where they will all support but push each other hard on a daily basis."

Kovacevic began his career with Sarajevo, winning the Bosnian Premier League twice, before moving to Poland for the first time and playing for Rakow Czestochowa.

He joined Sporting last summer but only made six appearances for the Portuguese club.

"For me, it's my dream to play in the Premier League and I think every Norwich fan wants to be there again," he said.

Norwich begin the new season with a home game against Millwall on 9 August.
