Was lucky to see Klose shoot wide after spilling an effort from Lulic but pulled off a great reaction stop to keep out the German's header later in the first half. Unfortunately for the Romanian, his touch on Candreva's cross proved fatal, as it left Lulic with a tap-in.
Struggled terribly to subdue Lulic, which ultimately proved decisive, but attacked well, setting up one decent headed chance for Destro after one of several surges down the right wing.
Made a crucial interception when Lulic looked to have picked out Klose at the near post but later lost the German and was fortunate that Lobont came to his rescue. However, he was excellent for the most part.
Very composed on the ball, the Brazilian rarely looked ruffled and dealt cleanly with every cross that came his way.
Picked up an early booking for chopping down Candreva but remained fiercely committed in the tackle. Got forward when he could - but to little avail, and was replaced by Osvaldo as Roma got desperate following Lulic's goal.
D. De Rossi
Passing was a little erratic in the opening quarter but did well to identify the danger being caused by Lulic and repeatedly got back well to help deal with the Bosnian. However, the goal eventually came from that very source and, fair to say, that De Rossi was just not at his best.
Involved in the move which put Bradley in on goal 10 minutes in but then collected the most senseless of bookings for booting the ball away. Remained a threat going forward, though.
Came in for some rough treatment but that did not stop him playing his part in the creation of a great chance for Bradley before then drawing a save from Marchetti. Looked capable of making something happen but his influence waned the longer the game went on.
Too loose in possession and really should have broken the deadlock on 10 minutes after a well-timed run into the area, but the American shot just wide.
Worked hard but only got his first sight of goal just before the break when he was unable to control his header, after being picked out by Marquinhos. Looked decent with the ball at his feet and managed a decent snap-shot in the second half, but it never looked like beating Marchetti.
His shooting was horribly erratic all evening but he did go close to equalising with a free kick that Marchetti lost in the air. However, this was not one of Totti's better derbies.
Dealt well with a low, bouncing effort from Totti and another daisy-cutter from Lamela early doors and continued in the same competent fashion thereafter up until the moment he was deceived by a Totti free and had to palm the ball up onto the bar. Decent showing, overall, though.
Beaten all ends up by Destro in the air just before the break, but got off the hook, with the forward heading over. Made amends, though, with a brave block on a shot from Marquinho just after half-time.
Did a fine job at the heart of the Biancocelesti defence, making numerous interceptions and well-executed challenges.
The Frenchman really put himself about, throwing himself in the way of one booming strike from Lamela and storming up-field whenever the opportunity presented itself.
The Romanian defended competently and also did well offensively, sending over the cross from which Klose should have opened the scoring.
Provided Lazio with plenty of dynamism in midfield, doing a fine job protecting his defence as well as driving forward with great regularity.
Booked inside the opening minute for an incredibly reckless foul on Lamela but he remained a feisty presence in the middle of the park before injury curtailed his evening.
The Brazilian playmaker wasn't afraid to stick the boot in and he was cautioned for a mistimed challenge on Lamela. However, he just did not create anything.
The Bosnian offered plenty of energy and incision down the left wing, and tested Lobont with a low curling effort from the edge of the area just three minutes in. He always looked the man most likely and duly scored the winner on 71 minutes, tapping home at the back post to put the seal on a fine performance.
Hacked down by Balzaretti early doors but the Italy international was still one of the most menacing players on the pitch and it was no surprise that the goal came from one of his crosses.
Had an early half-chance but he could only find the side netting after pouncing on a rebound and later saw his back-post header well saved by Lobont. Never really looked like his usual clinical self.
Used simply to waste a few seconds in injury time.
Saw six minutes of game time and made little impression.
Replaced the injured Ledesma early in the second half and played his part in Lazio's triumph, very nearly doubling their advantage just before the full-time whistle.
