Krøldrup, who spent four seasons with Udinese after leaving his first club B 93 København in 2001, made 91 Serie A appearances before moving to Goodison Park. He missed the opening two months of the campaign after undergoing a hernia operation and then struggled to earn a first-team place.
He played one league match on 26 December in a 4-0 defeat at Aston Villa FC, before a cameo as a substitute in the FA Cup win against Millwall FC last night. Fiorentina, who lost 3-1 at UC Sampdoria on Wednesday, are fourth in Serie A with 40 points from 20 games.
