Serie A preview: Top two seek to retain supremacy
AC Milan and Juventus are both in action on Saturday, and will surely hope to avoid the controversy that dogged their meeting last week.
The top two teams in Serie A clashed at San Siro last weekend, with league leaders Milan retaining a one-point advantage over second-placed Juve following a 1-1 draw between the two heavyweights.
Milan were aggrieved not to take a 2-0 lead in the match when the assistant referee failed to award a goal to Sulley Muntari.
The Ghana international's header appeared to have crossed the line by as much as a metre, only to be clawed out by Juve goalkeeper Gianluigi Buffon, subsequently fooling the match officials.
Buffon later stood by his actions, saying although he instinctively plucked the ball out of his goal, he would not have corrected the referee's mistake even if he had the opportunity to do so.
Milan's displeasure with the outcome is understandable - the reigning champions may continue to top the standings, but they have played one game more than Juve, who can move into first place with victories in their next two matches.
Next up for Milan is a trip to face eighth-placed Palermo, while Juve - still unbeaten in 24 league matches this season - host 10th-placed Chievo in Turin.
On Sunday, all eyes are likely to be on struggling Inter Milan and under-fire coach Claudio Ranieri.
Without a victory from their last eight matches in all competitions, Inter host mid-table Catania at San Siro.
The other big match of the day takes place in the capital, when fierce local rivals Roma and Lazio meet at the Stadio Olimpico.
Also on Sunday, Parma are at home to Napoli, Novara go to Bologna and Fiorentina host Cesena.
Lecce await the visit of Genoa, Cagliari travel to face Siena and Udinese are at home to Atalanta.
Later in the week, Juve visit Bologna on Wednesday in one of three fixtures rescheduled due to bad weather.
The other matches see Catania go away to Cesena, and Parma host Fiorentina.
