Watch as Lorenzo Venuti is caught napping for the decisive goal, though Udinese had other chances too and Fiorentina fired blanks again.
This is the fourth consecutive game between Serie A and the Conference League where the Viola have failed to score and it is beginning to turn into a real problem.
Their defence had been solid, but Venuti was caught napping by Gerard Deulofeu to set up Beto for the tap-in.
There were fine saves on Lucas Martinez Quarta and Deulofeu, while Isaac Success had his last-gasp goal ruled offside.
