Fiorentina want to sign outright Real Betis defender Germán Pezzella.

Pezzella is on loan at the Artemio Franchi from Betis and has become a key player in Stefano Pioli's side this season.

And La Viola are keen to bolster Betis' coffers as soon as possible, according to Fiorentinanews.com.

Chief among these is Atlético Madrid, who are in the market for defensive reinforcements in the summer and have put the 26-year-old at the top of their list.

While at Betis, Pezzella failed to impress Quique Setién and was loaned out to Fiorentina after failing to nail down a spot at the Villamarín.
