Fiorentina said they are set to sign Barcelona's Brazilian forward Keirrison on a two-season loan with an option for a permanent move.
The Seria A side, who need to reinforce their attack after Romanian talent Adrian Mutu's provisional suspension, said that the transfer will be completed if the player passes a medical on Monday.
"It's one player more, which we need at the moment," said Fiorentina coach Cesare Prandelli, whose side are fighting on three fronts - Serie A, the last 16 of the UEFA Champions League and the Italian Cup semi-finals.
The 21-year-old has spent the first half of the season on loan at Benfica.
Fiorentina, 11th in Serie A after Sunday's 2-2 draw at Cagliari, wanted to sign Antonio Cassano from Sampdoria, but the talented forward, who has had tense relations with coach Luigi Del Neri recently, decided to stay with the Genoa club.
