LECCE - Zlatan Ibrahimovic scored his seventeenth goal of the season, Luis Figo grabbed his first, and Dejan Stankovic got his fourth as a rampant Inter breezed to a 3-0 victory over Lecce at the Stadio Via del Mare.
The crushing victory sees Inter open up a temporary nine-point lead at the top of the table with AC Milan and Juventus still to play their Serie A Week 23 fixtures.
José Mourinho fielded a Christmas tree formation to face Beretta's Giallorossi, with David Santon making his fifth consecutive start at left-back and Materazzi returning from injury for his first start since last December's Champions League trip to Bremen.
Midfielder marauder Muntari returned alongside Zanetti and Cambiasso after a one-match ban, with Figo and Stankovic behind lone striker Ibrahimovic.
Inter took the game to Lecce and Ibrahimovic had an early chance before Stankovic headed over from close range.
Ibra gave his team a deserved lead on 12 minutes when he controlled Cambiasso's intelligent through pass and fired into the bottom left corner.
Lecce went close to an equaliser in the 18th, Stendardo rising at the back post to steer a downwards header on target at the back post that forced a reflex save from Julio Cesar.
Cambiasso tested Benussi before Ibrahimovic crashed wide from the edge of the area as the Nerazzurri created good chances to build on their lead before the break.
It was one-way traffic at the Via del Mare after the restart and Maicon incredibly blazed over, minutes before Stankovic was thwarted by Benussi.
Lecce's sole reaction was a solo move by their substitute Papadopoulos who ran into Julio Cesar after jinking past Cambiasso, Maicon and Burdisso.
With eighteen minutes left on the clock Figo found the bottom right corner with a stylish flicked header from Santon's pinpoint left-wing cross.
Stankovic celebrated his 200th outing for Inter in perfect fashion, nodding Maicon's cross into the top left corner to complete the rout on 82 minutes.
