Prince Gyimah‏: I could only master strength to work after that awful defeat to Tottenham only because most of my colleagues are United fans

Gregor Townsend has learnt from Manchester City manager Pep Guardiola as he looks to build a Scottish team full of "work-rate, energy and speed".

Townsend is preparing for his first autumn campaign as Scotland head coach, having succeeded Vern Cotter in May.

And the former fly-half says he is inspired by the methods of ex-Barcelona manager Guardiola, who led the Spanish club to 14 trophies in four years.

"I believe people watch Guardiola's attack more than his defence," he told BBC Radio 5 live's Rugby Union Weekly podcast.

"But his teams at Barcelona had a rule to win back the ball. They started at seven seconds, and then it went down to three seconds."

Stewart: As a Scotland supporter, I really hope Everton sack Koeman and hire David Moyes again.

Paul: If Koeman wanted all the mediocre players he's signed without addressing the lack of a decent no.9, then he has to be binned.

Arsene Wenger has taken his fair share of flack in the past few weeks, so here's a few stats to cheer him up.

Plus, Arsenal won on his birthday. What more could he ask for to celebrate his 68th?

• Arsenal have beaten Everton more times than any other club have beaten another in English Football League history (95 wins).
• Arsenal have now scored 100 Premier League goals against Everton, the first time a club has reached the landmark against one team.

Bournemouth manager Eddie Howe spoke to the press earlier today, before his side's Carabao Cup match against Middlesbrough on Tuesday.

Howe told reporters: "We'll have hesitation about changing the team [from the victory over Stoke]. In the last round we rotated and we came through the game and played very well.

"We played some good stuff at Stoke at the weekend. In the second half we showed resilience and did very well to see the game out.

"From leading positions we've lost points before, but I've never doubted the character of the players. It was good to get the win."

The Fifa's Best Awards are being held tonight in London.

There's the usual list of suspects but there's a few names you may not have heard of, including Venezuela's Deyna Castellanos.

She's nominated for the best female player - yet does not play in a professional league. In fact, she's never featured in an under-20s international tournament, never mind a senior one.

Andy White: Koeman is a good manager and Everton are a great club. Seems sad that a divorce is on the cards.

Despite speculation over his future after Sunday's 5-2 home defeat by Arsenal, the Dutchman took training as normal on Monday.

The Toffees are 18th in the Premier League and have won just two of their nine league games this season.

"I still believe I can change the whole situation," Koeman said on Sunday.

Here's an Everton stat that starts negatively and ends positively. Well. In a way.

• This is Everton's worst points tally (8) after nine games of a Premier League season since 2005-06 - when they had four points but finished the campaign in 11th place.

Martin Davies: Koeman has three games left. If no improvement, change him for Ancellotti or Thomas Tuchel. Not Moyes. Going back doesn't work.

Mikey Holloway: Koeman should be going now. Failed to find a ST. 3 Number 10s. Not playing wingers. Playing ppl out of position
