Barcelona's Brazilian striker Keirrison will join Fiorentina on loan until June 2011.

The Serie A outfit has confirmed an agreement has been reached with Barcelona to bring Keirrison to Florence. Keirrison becomes the sixth reinforcement for the Viola in the winter transfer window.

A statement from Fiorentina read: "Fiorentina announce they have reached an agreement with Barcelona for the temporary acquisition of Keirrison for the next two seasons.

"The deal will be completed after the player passes a medical in the next few hours.''

The 21-year-old Keirrison joined Barcelona last summer on a €14 milllion transfer deal from Palmeiras.

He was loaned to Portuguese side Benfica earlier this season.

The South American is under contract with the Primera Division champions until June 2014.

Fiorentina have released midfielder Martin Jorgensen from his contract, at his request.

The veteran Danish midfielder wants to play for his country at this summer's World Cup, and is expected to resume his career with Aarhus in his homeland.

Jorgensen, 34, also began his career at Aarhus before lengthy spells in Italy with Udinese and Fiorentina.

He feared seeing little action with Fiorentina in the remaining months of the season, and said: "That would have compromised my participation in the forthcoming World Cup which will be the last of my career."
