Atletico, who secured a UEFA Champions League spot after finishing fourth in the Primera Liga t able, stepped in to sign Ujfalusi.

"Fiorentina want to show its gratitude for Ujfalusi and wish him the best of luck in future," the Italian side said in a statement on their website.

"A man of his quality will be always appreciated everywhere. Thanks Tomas, thanks again and good luck."

The 30-year-old is Atletico's second signing for the new season following the arrival of Ajax defender John Heitinga.
