Swiss midfielder Valon Behrami ensured it is advantage Lazio at the half-way stage of their Coppa Italia quarter-final against Fiorentina.
Two goals in as many minutes ensured Delio Rossi's side take a 2-1 lead into the return leg in Florence.
A partisan Stadio Olimpico crowd were off their feet in the 19th minute when Aleksandar Kolarov's free-kick deceived Viola goalkeeper Cristiano Lupatelli.
And just a minute later it was double delight for Lazio as an unmarked Behrami exposed poor Fiorentina marking to register his side's second.
Massimo Mutarelli struck the bar for a rampant Lazio, before on the counter-attack Giampaolo Pazzini made for an interesting second leg when he finished with poise to reduce the deficit.
