Inter visit Sampdoria in Serie A opener

(CNN) -- Serie A champions Inter Milan will open the defense of their title with a trip to Sampdoria on August 31 but the match of the opening weekend will take place in Florence where last season's third-placed Juventus will face Fiorentina, who were fourth.

Ronaldinho's first match in an AC Milan shirt could be against Bologna, the visitors to the San Siro on the opening weekend.

Jose Mourinho's Inter will have a low-key start to their campaign until September 28 and the Milan derby on the fifth weekend of the season.

Just three weeks later on October 19 Inter will travel to Roma in one of the most important clashes in the title race -- a fixture they won 4-1 last season.

Should Milan and Roma be involved in the championship race right down to the wire, they face a potential title decider in Milan on the penultimate round of matches in May.
