Milan - Juventus ease to a 2-0 win over Spal as Gianluigi Buffon made Italian soccer history.
Alexis Sanchez scored on his first start but was also sent off as Inter Milan won 3-1 at Sampdoria on Saturday to maintain their perfect opening to the Serie A season.
Sanchez was involved in Stefano Sensi's goal before getting on the scoresheet himself. However, the Chile forward was sent off at the start of the second half after receiving a second yellow card for simulation.
Jakub Jankto got one back for Sampdoria but Roberto Gagliardini restored Inter's two-goal advantage.
It was Inter's sixth win from the opening six matches and the perfect way to head into a crucial week.
Antonio Conte's side visits Barcelona in the Champions League on Wednesday before hosting eight-time defending champion Juventus four days later.
Inter dominated from the start and took the lead in the 20th minute when Sensi's snapshot was deflected into the bottom corner.
Two minutes later Sanchez tapped in Sensi's wayward effort. It was his first goal for Inter since joining on loan from Manchester United in August.
Sampdoria was offered a way back when Sanchez was ordered off after diving in the penalty area in the opening minute of the second half.
And it reduced the deficit eight minutes later when Jankto fired into the bottom corner.
However, its hopes were swiftly dashed in the 61st as Gagliardini's initial effort was saved by Samp goalkeeper Emil Audero but he tapped in the rebound.
Juventus eased to a 2-0 win over Spal as Gianluigi Buffon made Italian soccer history.
Miralem Pjanic and Cristiano Ronaldo scored and it would have been worse for Spal without goalkeeper Etrit Berisha keeping the Bianconeri at bay.
At the other end, Buffon was appearing in his 903rd club game as he surpassed Paolo Maldini's record for an Italian player. With six more appearances, Buffon can break Maldini's mark for most games played in Serie A.
He was barely called into action on Saturday and his opposite number was certainly the busier keeper.
Berisha pulled off an extraordinary save to keep out Aaron Ramsey's header from point-blank range in the 43rd minute but Juventus broke the deadlock two minutes later.
Berisha could only push Blaise Matuidi's cross away and Sami Khedira knocked it down for Pjanic, whose effort was deflected into the top corner.
Ronaldo was denied on several occasions but finally got his goal in the 78th when he powerfully headed in a delightful cross from Paulo Dybala.
It was Ronaldo's third goal in his five Serie A matches this season.
Juventus has five wins from six matches. The result will help Juve's confidence ahead of Tuesday's Champions League match at home to Bayer Leverkusen.
