Italian World Cup champion Marco Materazzi, who was on the receiving end of Zinedine Zidane's head butt in the World Cup final, scored both goals to give Inter Milan a 2-1 win at Siena on Sunday and clinch its 15th Scudetto. It is Inter's first title on the field since 1989. Inter was awarded last year's title when a sports tribunal revoked Juventus' title win in the fallout from the country's match-fixing scandal.
Like Inter, Lyon had blown a chance to clinch the title at home on Wednesday and celebrated with champagne on Saturday night at its Auxerre hotel when second-place Toulouse lost at home to Rennes, 3-2. Lyon, which was held to a 0-0 tie at Auxerre on Sunday, clinched a sixth Ligue 1 title -- a record for a major European league. Only Rosenborg has done better in Europe, collecting 13 Norwegian titles from 1992 to 2004.
Celtic clinched back-to-back Scottish Premier League titles on Sunday when Japanese star Shunsuke Nakamura scored with a brilliant free kick in stoppage time to seal a 2-1 win at Kilmarnock.
Olympiakos made sure of its ninth Greek league title in 10 years when it beat Kerkyra, 3-1.
