The fee, which at a reported £9.5million surpasses the £8m paid for Steven Caulker, sees the Chile international midfielder provide Malky Mackay with further attacking options as they prepare for their first Premier League campaign.

Medel has agreed a four-year deal at the club subject to a work permit being granted.

The 26-year-old joined Sevilla in January 2011 and made 94 appearances for the Liga side, scoring nine goals, seven of which came last season.

Mackay was happy to have captured the winger and is in no doubt that he will be able to handle the move to England.

"We're delighted to have secured the services of Gary - a tenacious and intelligent international midfielder," the Cardiff manager told the club's official website.

"Having had two seasons of regular football in La Liga - with 60 odd international caps to his name and three appearances at a World Cup - his experience will be an invaluable asset to our squad.

"He's played in a number of Boca v River Plate derbies in Argentina - one of the world's biggest derby matches - and I've no doubt that his background and pedigree will complement our midfield group in the Barclays Premier League."

Medel joins Caulker, Andreas Cornelius, who joined for £7.5m, John Brayford, and Simon Moore as new arrivals at the newly promoted side.
