Turin, Italy (SportsNetwork.com) - Juventus and Roma will both aim to maintain their perfect records in Serie A on Sunday when the two title favorites clash at Juventus Stadium.

Juve has captured the past three league titles, and Massimiliano Allegri's men are firm favorites to add a fourth straight this season, with Roma looking to be the biggest threat to the Old Lady.

Both teams have started the campaign with five wins from five fixtures, and Juve has yet to concede a goal, while Roma has given away just one.

Last term it was Roma that pushed Juve to finish line, only to come up a bit short, and Rudi Garcia's men will look to lay down an early marker on Sunday to continue their good start.

Roma has yet to taste defeat in all competitions after earning a 1-1 draw at Manchester City in the Champions League on Tuesday, while Juventus suffered its first setback on Wednesday in a 1-0 Champions League loss at Atletico Madrid.

Despite that setback, Allegri is confident heading into one of his side's most important games in Serie A this season.

"Juve arrive in good shape, as we won all five in Serie A and still haven't conceded there," Allegri said on Wednesday following the setback to Atletico.

"It will certainly be a great game and tonight's defeat will not change the atmosphere in the team."

Udinese has started well with four wins from five games and the team's lone defeat came to Juventus. That good start has a strong chance to continue on Sunday with a home match against Cesena, which owns one win from five games.

Sampdoria is the only other unbeaten team in Serie A and the club will put that mark on the line against 16th-place Atalanta at home.

Inter Milan sustained a humbling 4-1 home defeat to Cagliari last weekend, and the Walter Mazzarri's side will aim to bounce back at mid-table Fiorentina, while AC Milan hopes to end a three-game winless run in the league when the Rossoneri entertain Chievo.

Hellas Verona has started well with eight points from five games and the team hosts Cagliari, Empoli and Palermo square off with both sides searching for their first win of the season, Lazio entertains last-place Sassuolo, Genoa invades Parma and Napoli tangles with Torino.
