The Los Angeles Clippers extended their impressive run of form with a 123-110 win at New Orleans on Monday, maintaining a three-game lead atop the NBA Pacific Division, thanks chiefly to Jamal Crawford's 7 3-pointers.

Visibly upset after Mexico was eliminated from the 2010 World Cup in South Africa in the round of 16, long-time captain Rafael Marquez announced he had just played his last international.

Matias Fernandez's stunning free kick saw Champions League-chasing Fiorentina snatch a 2-2 draw at Parma in a thrilling Serie A match which also featured three red cards on Monday.

Barcelona paid 13.55 million euros ($18.6 million) to Spanish tax authorities on Monday to cover any potential irregularities in its signing of Neymar, all the while maintaining its innocence of the fraud charges levied against it.

The Spanish champion said in a statement it had paid the "complimentary" amount to cover any "eventual interpretations that could come out of the contracts signed relating to the transfer of Neymar. Meanwhile we are convinced of the legality of our initial fulfillment relating to our tax obligations."

By the busload, the world's athletes and visitors rolled toward Sochi's airport and took off for home Monday, fresh from a Winter Games experience that many Russians pronounced a smashing success and that the Olympic movement's chief enthusiastically labeled a victory for the region and the host nation.

After 17 days of global sport and spotlight, Sochi ended the spirited chants of "Ro-ssi-ya! Ro-ssi-ya!" and started cleaning up.
