High on a barren mountainside, a red flag marks the spot where China hopes ski jumpers will launch themselves to glory at the 2022 Winter Olympics. But hosting the Games would require a giant leap of its own.

For now, the bitterly cold valley is home to Taizicheng, a sleepy community of about 100 houses where traditional Chinese music drifts on the biting wind. On the opposite hillside -- where biathletes would race and shoot -- peasants weighed down by loads of firewood are the only sign of life.

Palestine coach Ahmad Alhasan invited Australia to visit the Palestinian territories for a rare and unlikely friendly set against the backdrop of Israeli occupation.

Djokovic won the first of his seven major titles at the 2008 Australian Open, then won here in three consecutive years from 2011 to 2013. His 25-match winning streak at Melbourne Park ended in a quarterfinal loss last year to Stan Wawrinka, who went on to win the title.

Substitute Moussa Sow snatched a stoppage-time winner as Senegal hit back to defeat Ghana 2-1 Monday in the Africa Cup of Nations Group C opener.

Liverpool manager Brendan Rodgers is confident his side can put their recent run of results against Chelsea behind them when they face the Premier League leaders' in the first leg of an English League Cup semi-final at Anfield on Tuesday.

Rodgers has lost all three of his matches against Chelsea mentor Jose Mourinho since moving to Merseyside but believes talk of a tactical battle is exaggerated.

Chelsea manager Jose Mourinho has said failing to sign Steven Gerrard remains one of his greatest regrets as he urged Blues fans to stop mocking the Liverpool captain.

The two Premier League clubs will clash again when they meet at Anfield on Tuesday in the first leg of a League Cup semi-final, with Gerrard having already announced he will leave Merseyside at the end of this season to join U.S. Major League Soccer side LA Galaxy.

It could be the bumbling defending, or perhaps the vanishing spray has a mysterious side-effect, but the Asian Cup has yet to produce a draw in 20 matches -- now officially a record at major football tournaments.
