Marc Marquez has his first shot at retaining the MotoGP championship this weekend at the Motegi circuit in Japan. It is the first of four races left in the season.

The Spaniard has a 75-point lead over his Repsol Honda team-mate Dani Pedrosa and a 78-point lead over Yamaha's Valentino Rossi. A race win for Marquez would see him take the title whatever happens behind him.

Marquez has won 11 of the 14 races so far this season, including a record-equalling 10 in a row, with Pedrosa, Rossi and Lorenzo having won just one each.

He crashed out in the first practice session on Friday but recovered to set the second-fastest time with only compatriot Jorge Lorenzo able to out-pace him on his Yamaha. Marquez was then sixth fastest in the afternoon.

More than 100 football fans have been detained in Belarus after nearly the entire stadium joined in chanting a well-known song insulting Russian President Vladimir Putin, media reports say.

Both local and visiting fans at the Euro 2016 qualifier between Ukraine and Belarus in Borisov came together in a rousing rendition of the song - which has became a popular expression of opposition to Putin in Ukraine, the Belarusian paper Nasha Niva reports.

After the match, about 100 Ukrainian and 30 Belarusian were held and taken to the local KGB station, reportedly on suspicion of using "obscene language", the opposition website Charter '97 reports. According to one report, some of them will be taken to court and are expected to receive a five-day sentence. The Ukrainian fans will also be deported.

It may be four months until jump racing's Cheltenham Festival, but champion trainer Paul Nicholls is looking forward to glittering prizes ahead for Wonderful Charm after the gelding took the most valuable - and highest quality - race staged at Newton Abbot, the £30,000 Intermediate Chase.

The 100-30 shot, the mount of Nicholls' new no. 1 jockey Sam Twiston-Davies, had three lengths to spare over favourite Colour Squadron, the sport's highest-rated novice chaser, ridden by Tom O'Brien in place of the injured AP McCoy. Cheltenham Gold Cup hope Taquin Du Seuil was third.

Nicholls said: "That's as soft [going] as you'd risk him on. He really wants it much better. We'll look at a race at Down Royal next month for him, but he won't run if it's too soft, and there will be plenty for him in the spring in the Ryanair [at Cheltenham] and at Aintree."

In 2013, India batsman Sachin Tendulkar announced he would retire from all forms of cricket after his impending 200th Test.

AC Milan director Umberto Gandini believes Champions League wildcards should be introduced to ensure some of Europe's biggest clubs do not miss out.

Currently, the Premier League top three qualify automatically, with the side in fourth entering the play-off round. In Italy, the top two go straight into the Champions League, with third going into the play-offs.

"I think we have to look at ways of improving the Champions League," Gandini told BBC World Service.

How about this for boosting your players' confidence? Martin O'Neill has told his Republic of Ireland squad that they are "not good enough to be complacent" when they face Gibraltar in Dublin on Saturday.

"We, seriously, will not be good enough to be complacent, certainly not," he said. "We are expected to win, don't get me wrong. There's a difference. We might not be able to break them down as easily as one might think."

Northern Ireland's players are relishing the opportunity to demonstrate their attacking capabilities against the Faroe Islands, says manager Michael O'Neill.

Having won 2-1 in Hungary in their first Euro 2016 qualifier, hopes are high for a comfortable win on Saturday.

"There has been a lot of focus on our attacking play especially, our approach has been slightly different," O'Neill said. "You just can't go out and play off the cuff and play in a cavalier fashion. But this is an opportunity to show the other side to their game."

The Newcastle Chronicle reports, external that Mike Ashley is planning to remain in charge at St James Park until at least 2016, despite his growing influence at Rangers.

Ashley has increased his shareholding in the Ibrox club. The rules state that he can own 49.9% of a club and own another that potentially could play one another in a European competition.

Stephen Quinn says the Republic of Ireland must not get too frustrated if they don't have early success against Gibraltar in tomorrow's Euro 2016 qualifier.

The Republic won 2-1 in Georgia in their opening qualifier, Gibraltar lost 7-0 at home to Poland, though they were only a goal behind at half time.

The Hull City midfielder said: "We don't know too much about them. We watched the first half of the game against Poland and they were quite rigid. We have to be patient and the crowd have to be patient with us as well."

Stoke captain Ryan Shawcross insists he is not considering switching allegiance from England to Wales despite being overlooked by Roy Hodgson.

The 27-year-old centre-back won his solitary cap as a substitute in a friendly against Sweden in 2012 but has not been called upon in a competitive game so is still eligible to play for Wales.

"I made a decision a couple of years ago to play for England. I've got one cap and I want more. If it happens, it happens," Shawcross told the Stoke Sentinel. "If I don't get into the England squad until I retire, I will have no frustration. I'm just happy to be playing."

"The car felt really good. We've quite a good balance, so there are a lot of boxes ticked, but we still have work to do to see if we can improve."
