Gonzalo Rodriguez's first-half finish has handed Fiorentina a 1-0 half-time lead over hosts Chelsea in their friendly clash at Stamford Bridge.
Fiorentina pushed for an opener from the off and Asmir Begovic was called into some early action as he had to keep out a strong effort from Matias Fernandez down low.
Chelsea youngster Ruben Loftus-Cheek appeared out to impress Jose Mourinho and he came close not too long after with a skilful effort that was blocked smartly by Facundo Roncaglia.
The home side looked to gain control of the game, but they were dealt a major blow in the 34th minute when Rodriguez stabbed home past Begovic, having reacted well from Marcos Alonso's saved effort.
Mourinho's men might have found an equaliser before the break when Fiorentina keeper Luigi Sepe was sent a poor back-pass, but the stopper recovered well to prevent Radamel Falcao capitalising from close range.
