Fiorentina maintained their pursuit of the Serie A title as a late flurry of goals downed 10-man Atalanta 3-2 in Bergamo.
The first of five strikes arrived in the 67th minute as Mati Fernandez gave the Tuscans the upper hand, with Barcelona loanee Cristian Tello firing Fiorentina two goals clear nine minutes from time.
Atalanta refused to roll over and halved the deficit through young defender Andrea Conti, who would later be dismissed in stoppage time.
Substitute Nikola Kalinic then grabbed what proved to be Fiorentina's winner and Mauricio Pinilla wrapped up the scoring with Atalanta's second at the death.
