Lions 2013: Why Will Genia is key to Australia's series hopes
British and Irish Lions coach Warren Gatland will have thought long and hard about Will Genia over the past few months.
He may even have had the occasional sleepless night, woken by images of the Wallaby scrum-half piercing another hole in his defence. Between now and the start of the first Test on 22 June, The Genia Problem will be looked at again and again by the Lions.
Nick Farr-Jones, one of the greatest scrum-halves of all time, told BBC Radio 5live: "If Genia has an outstanding game, the opposition have lost, and the Australians need him to perform in order to win."
Ruthless Perez unfazed by critics
Sergio Perez is not winning many friends in Formula 1 at the moment - at least not with the established stars among his fellow drivers - but he is certainly making an impression.
The 23-year-old Mexican, the man McLaren chose to replace Lewis Hamilton, has attracted the disapproval of all F1's former world champions bar one with some robust driving in recent races and he seems not remotely bothered about it.
Perez's tactics were the subject of discussion at the drivers' briefing in Bahrain following incidents in China and in Spain following more in Bahrain. He may well be brought up again this weekend in Canada after Lotus's Kimi Raikkonen said following the Monaco Grand Prix that"someone should punch him in the face".
That remark was most unusual from a man who is notorious for keeping his thoughts to himself in the presence of the media and it made clear just how angry Raikkonen was about what had happened in the race.
The two drivers collided when Perez tried to overtake Raikkonen's Lotus on the run to the chicane late in the race, the same place he had previously passed his team-mate Jenson Button and had been involved in a mildly controversial incident with Ferrari's Fernando Alonso
