Mirko Vučinić praised a "united" and "wonderful squad" after Juventus reclaimed the Serie A leadership from fellow winners AC Milan with a spirited 2-1 victory against FC Internazionale Milano at San Siro.

The Montenegrin international had set the ball rolling with a 12th-minute strike and although Maicon equalised on 28, Claudio Marchisio grabbed the winner five minutes later. The Derby d'Italia victory took the Vecchia Signora two points clear at the summit and left the Nerazzurri just two points above the bottom three.

"It's too early to talk about winning the Scudetto," said Vučinić. "We have to prove our strength in the next game against Napoli. If we lose that match then tonight's victory will be wasted. Consistency is key. We have great players. However, you can have as much quality as you want but you cannot go top of the table if the squad is not really united and ours is a wonderful squad."

Milan had put the pressure on the pacesetters with a 3-2 victory at AS Roma. Zlatan Ibrahimović (17, 78) scored either side of a rare Alessandro Nesta strike (30) – his seventh league goal in his tenth season at the club. Although Bojan Krkić (87) added to Nicolás Burdisso's effort (28), the Italian champions held on.

Elsewhere, SSC Napoli warmed up for Wednesday's UEFA Champions League trip to FC Bayern München with a 2-1 loss at Calcio Catania. Giovanni Marchese (25) and Gonzalo Bergessio (48) rendered Edinson Cavani's first-minute goal academic.
