Inter Milan captain Javier Zanetti is glad to have Jose Mourinho back on the bench for Saturday's Serie A match at Palermo.

The Nerazzurri beat Mourinho's former club Chelsea 1-0 at Stamford Bridge on Tuesday night to claim a 3-1 aggregate win and progress to the quarter-finals of the Champions League for the first time in four years.

That game marked Mourinho's return to the touchline, the Portuguese coach having served a three-match ban in the league. And his absence has been felt as Inter have collected just four points from those games.

"Mourinho helps us to win," said Zanetti.

"He is very experienced and his support is very important to us."

On the win over Chelsea, the Argentinian added: "I think we have sent out an important message. To beat (Chelsea manager Carlo) Ancelotti's team twice is quite an achievement."

The Nerazzurri will have to put the euphoria of knocking out Chelsea behind them and focus on the Palermo game as AC Milan are breathing down their necks.

Should Inter fail to win, Milan could move above their city rivals and into top spot for the first time this season.

Milan edged Chievo 1-0 last weekend after the Nerazzurri lost 3-1 at Catania, and that win helped the Rossoneri to narrow the gap on Inter to just one point.

While Inter will be tested by a Palermo side that have yet to lose at La Favorita this season, Milan take on Napoli at the San Siro hoping to overcome the losses to injury of David Beckham and Alessandro Nesta.

England midfielder Beckham tore his Achilles tendon last weekend and will miss the rest of the season and the World Cup, while Nesta is out for a month with a knee injury.

"We hope their absences will give us more strength to repay their efforts with many more wins this season," said midfielder Clarence Seedorf, who scored a stoppage-time winner against Chievo.

Roma are at home to Udinese and looking to get back in the title race after last weekend's 3-3 draw at Livorno.

They are in third place, six points behind Inter with 10 games remaining.

Juventus, who make the journey to Genoa to face Sampdoria, will be looking for a helping hand from Inter as they bid to climb into fourth place.

The Bianconeri, who threw away a three-goal lead and had to settle for a point at bottom-side Siena last weekend, are one point adrift of Palermo, who the last Champions League qualifying spot.

Fiorentina host Genoa at the Artemio Franchi stadium on Sunday with both clubs vying for a place in Europe next season.

The Viola are four points behind seventh-placed Genoa.

Bari and Parma meet at the San Nicola, while Lazio travel to Cagliari knowing a defeat coupled with a Livorno triumph at Atalanta could see them drop into the relegation zone.

The Rome outfit have failed to win in their last four games and are two points clear of 18th-placed Livorno.

Chievo will be desperate to avoid their third straight defeat when they take on Catania in Verona.

Siena take on Bologna looking to extend their unbeaten run to six games.

The Tuscan outfit are four points adrift of safety.
