MILAN, Italy -- Inter Milan won its 15th straight game in the Italian league by stopping Chievo Verona 2-0 in a stadium without fans, and Ronaldo made his debut in AC Milan's victory.
The Serie A resumed Sunday, more than a week after all professional soccer in Italy was suspended for fan violence.
Adriano put Inter ahead in the first minute with a shot from the left edge of the penalty area and Hernan Crespo added the second in the 51st.
The game was one of four in Serie A played in an empty stadium. The stadiums had failed to meet new security standards put in place after the death of a police officer in rioting at the Catania-Palermo game Feb. 2.
Ronaldo, wearing the No. 99 jersey, came on as a substitute in the 63rd minute for his first appearance for Milan since joining from Real Madrid last week. Milan beat Livorno 2-1.
Inter leads the league with 60 points, 11 more than second-place AS Roma, which beat relegation-threatened Parma 3-0. Palermo, which lost to fourth-place Empoli 1-0, is third with 42 points.
Milan, which started the season with an eight-point penalty from the Italian game-fixing scandal, climbed to seventh place with 30 points.
LONDON -- Tomas Rosicky headed in the winner with five minutes remaining and Arsenal rallied to beat Wigan 2-1 to remain in fourth place in the English Premier League.
Denny Landzaat's goal in the 35th minute put Wigan ahead at Arsenal's Emirates Stadium. The Gunners, who were in danger of slipping to fifth, tied the score with nine minutes to go when Wigan defender Fitz Hall turned a cross from Mathieu Flamini into his own net.
Rosicky's winner gave Arsenal 49 points, 17 behind leader Manchester United, 11 adrift of Chelsea and one back of Liverpool.
In Sunday's other Premier League game, Gary Speed and Kevin Nolan scored a goal each to give Bolton a 2-1 victory over Fulham and keep the Wanderers on course for a place in European competition next season.
AMSTERDAM, Netherlands -- Ajax defeated ADO The Hague 2-1 to move within three points of Dutch league leader PSV Eindhoven.
John Heitinga and Klaas-Jan Huntelaar scored in the second half for second-place Ajax.
PSV, winless in three games, was held to a 1-1 tie by Sparta Rotterdam. Jason Culina gave PSV the lead in the 46th minute, but Haris Medunjanin tied it in the 76th.
GLASGOW, Scotland -- Rangers got a hat trick from Kris Boyd in its 3-1 win over Kilmarnock in the Scottish Premier League.
Boyd sandwiched penalty kicks around a 30th-minute header. Steven Naismith scored in the 73rd minute for the hosts.
Celtic, which beat Hibernain 1-0 Saturday, leads the league with 68 points, followed by Rangers with 49.
