Euro 2012 will not be a cakewalk for holders Spain and in-form Germany, German coach Joachim Loew said on Wednesday, insisting other nations such as France had to be considered.

"It's not certain this match (a Germany versus Spain showdown) will happen at this tournament -- even if everyone is talking about this duel," Loew told reporters who asked him to compare his side's chances with those of the defending European and world champions.

The euphoria of Argentina's opening World Cup qualifying win over Chile vanished at a stroke on Tuesday as the two-time world champions slumped to an historic 1-0 loss to Venezuela.

Serena Williams could get a chance of revenge against Samantha Stosur on the Australian's home soil after announcing she will start her 2012 season at the Brisbane International.

Lebanon conceded a late own goal to draw 2-2 with Kuwait in third-round Asian qualifying for the 2014 World Cup on Tuesday.

In-form Andy Murray said Tuesday he had entered the final weeks of the season in a good "mindset" as he bids to dislodge Roger Federer from the world number three spot.

Britain's Murray has won 21 of his past 22 matches, taking titles in Cincinnati, Bangkok and Tokyo. His only loss during that period came against Spain's Rafael Nadal in the US Open semi-finals.

Rafael Nadal refused to be drawn Tuesday over any potential meeting between players in Shanghai this week to discuss the punishing demands of the tennis schedule.

America's Andy Roddick said Monday that Shanghai Masters no-shows from world number one Novak Djokovic and 16-time Grand Slam champion Roger Federer were stark evidence of the toll put on players by heavy playing commitments.
