Andre Emmanuel: Jose Mourinho. He never should have returned to Chelsea. Now he is undoing all the good work, and the goodwill he had built with Chelsea fc supporters round the world. Mourinho must accept his limitations as a manager. he can't succeed in the third year managing the same club.

World champion Gary Anderson has revealed he deliberately lost a Premier League match against Adrian Lewis at Glasgow's SECC in 2011.

Scot Anderson, 44, led the match 3-0 but, with Lewis suffering "disgraceful" abuse, allowed the Englishman to reel off eight legs in a row to secure an 8-3 victory.

Asked if he intentionally lost, Anderson told BBC Scotland: "Yes. I didn't want to win a game where that happened. I thought it was a disgrace."

Lewis, 30, had beer thrown at him during his entrance to the arena, and coins were thrown onto the stage during the match.

Manchester City face Borussia Moenchengladbach in the Champions League tomorrow and midfielder Yaya Toure, who missed the weekend defeat at Stoke, has trained this morning.

Sergio Aguero, skipper Vincent Kompany, Martin Demichelis and Fernando all missed the session, however.

City have qualified for the knockout stages but to top the group they must defeat the Germans and Sevilla must beat Juventus.

You may recall the name Holly Holm.

She was the American who floored Ronda Rousey to win the mixed martial arts championship in Melbourne last month.

It was a massive shock as Rousey was thought unbeatable after going undefeated in her first 12 mixed martial arts fights, with 11 of those wins in the first round.

The reason for mentioning all this? Holm has arrived back in her home city of Albuquerque, New Mexico, and the reaction was quite something...

Michael Barnsfield: Ronnie O'Sullivan coming back after a year without playing Snooker and winning the World Championship. Not once but twice.

Keaton Shaw: Scholesy. Retires, comes out of retirement, wins league. Only one of the best midfielders to ever grace the league could do that. 

Andrew Webb: Nigel Pearson at Leicester - mid table finish in his first season back - then got us to play-offs to lose in dramatic style to Watford. Season three the championship title, and season four survival in the Premier League despite being bottom for so long.

Sir Alex Ferguson is in no doubt Jose Mourinho will revive Chelsea's flagging fortunes. The reigning champions have lost eight of their first 15 games and languish in 14th place but Ferguson said: "There are signs he is getting back to a balanced level although they lost on Saturday. 

"I think all good leaders will eventually find a solution. I know the guy and I know the work he has done in football and I can't see it lasting long, I can't see it."

We're no experts but we reckon Pittsburgh Steelers' Antonio Brown may regret the way he celebrated his touchdown against Indianapolis Colts.

After running the length of the pitch to score his third touchdown of the match, Brown flung himself legs wide apart against the post in what, for most men, would be an eye-watering moment.

The officials were unimpressed by his choice of celebration, handing him an unsportsmanlike penalty for "using the goalpost as a prop".

You can watch a clip of the touchdown and celebration here.

Wayne Rooney and Morgan Schneiderlin are not with them but Manchester United head off for their key Champions League game with Wolfsburg.
