A parting message from IBF world welterweight champion Kell Brook.
Until next time, goodnight. Stay across the BBC Sport website for reaction and follow-ups on this latest Brook win.
Thank you for being with us.

Kell Brook dazzled, not least with the gold trim on his shorts, sizing up his opponent early in round one and then quickly exploding to deliver the goods.
Two knockdowns in round two, another two in round four and that was that. Jo Jo Dan found sanctuary in his corner and his entourage decided he would not come out to take any more punishment.
Brook's right hand looked superb. Accurate, powerful, damaging. To think there were concerns over his balance when he was stabbed in the leg back in September. The only one with balance problems tonight was Jo Jo Dan. It looked like he had silk socks on while dancing on a polished floor.
Elsewhere in the world of boxing this week it has emerged tax authorities are chasing Manny Pacquiao for £33m,, external hardly ideal when he is about to glove up for arguably the biggest fight in boxing history.
His opponent on 2 May, Floyd Mayweather, was knocked down in training by sparring partner Zab Judah if Twitter gossip is to be believed but Judah denies it happened., external

Warrington, who contests for the WBC International featherweight title at Leeds Arena, is a huge Leeds United fan.
Jones is not the first sportsman to accompany him to the ring as former footballer Dominic Matteo and Super League star Jamie Peacock had the honour when the 24-year-old last fought at home in October.
Image source, Getty Images"I've come a long way, fighting on undercards and in leisure centres to packing out this arena as a world champion," said Kell Brook on Friday.
The champion is not wrong and a look back at his first fight throws up a story that even stone-hearted individuals will love.
On that September night in 2004, Brook went toe-to-toe with Peter Buckley - a man with 189 losses in 220 fights at the time. Buckley was consistently brilliant at losing and recently told BBC Sport that getting beaten is an art which pays the bills.
Peter 'The Professor' Buckley continued and eventually retired on 300 fights - 256 were losses. Why is this heartwarming? Because the pro went out with a win in 2008, his first in five years.
Hugh Lawrie, star of American TV drama House and BBC classic comedy Blackadder, takes to Twitter:, external Huge congratulations to Kell Brook. And Jo Jo Dan heroic to stand even a minute of that.
Timely from three-time world champion Adrien Broner. The man dubbed 'The Problem' takes to Twitter to further stir the Amir Khan, Kell Brook pot.

Image source, Matchroom SportFlyweight Yafai, 25, did well to inflict only the second defeat of Rosales's 12-fight professional career.
Yafai, who moved down from super-flyweight for this fight, has now won all 14 of his professional bouts, with nine of those victories coming inside the distance.
Promoter Eddie Hearn and cruiserweight are chewing the fat on a potential Brook-Khan clash on BBC Radio 5 live:
Eddie Hearn: "Amir Khan will probably announce next week he will fight Chris Algieri."
Tony Bellew: "What for though? Algieri has just been bounced off the floor 25 times by Manny Pacquiao."
Eddie Hearn: "I believe Amir Khan v Kell Brook does Wembley."
Tony Bellew: "It sells immediately, it's a huge, huge fight."
Sheffield - 'the steel city' - makes men of steel.
Image source, Getty ImagesThanks in no small part to the training of Brendan Ingle, fight fans in the city have been able to welcome a string of world champions home.
They include WBO, IBF and WBC featherweight champion Prince Naseem Hamed (right), ex-WBO cruiserweight champion Johnny Nelson (centre), WBO light middleweight champion Paul 'Silky' Jones and IBF light heavyweight champion Clinton Woods.
Herol 'Bomber' Graham (left) - acknowledged as one of the best British boxers of the post-war era never to have won a world title - is also from the northern city.
Ingle's fighters are known for relying on footwork and speed for defence rather than a rigid guard, freeing their hands to launch attacks.
The latest champion from their stable - Kell Brook - exuding such qualities tonight. He floated and smashed wonderfully.
Image source, PASome more quotes from Kell Brook. "If you're watching Amir Khan, then get in here with me. I know you're delicate around the whiskers.
"I've come from a council estate, now I'm world champion and defending my title. I've made it. I've come from the bottom and I'm at the top.
"I didn't think I would walk again, never mind box again. Now I'm here defending my title."
Kell Brook's promoter Eddie Hearn wants Brook to fight Amir Khan at Wembley in June.
Hearn said: "There's a venue available on June 13. If Amir Khan is watching give everyone what they want. He doesn't have an opponent and he is talking about fighting boxers lower than Kell. It's the biggest pay day available and it's for a world title."
Kell Brook marches back through the hallways of the Motorpoint Arena, congratulations pouring the way of the champion.
JessiJackalope: Respectful call by Dan's corner. Brook looked superb but I'm not sold on a clash with the May-Pac winner. Great comeback
Andrew Priestley: We've just witnessed Kell Brook absolutely dismantle Jo Jo Dan. Big, big things lie ahead for this man. Fantastic performance.
Image source, PAKell Brook says: "It was amazing to be able to walk to the ring again and this is where I belong. I didn't think I would box again, and I can't put into words what it means to defend my title. It was hard holding it together.
"I'm sorry I kept you waiting, but I'm back, baby.
"What a heart he had, I caught him with some good, clean shots. but you're seeing signs of greatness, but there's lots more to come from me. My leg feels as good as the other leg."
Boxing loves a legend. Boxers seek a legacy. Few manage it.
Image source, Getty Images"I want to be remembered like a Tyson, a Sugar Ray Leonard, a Sugar Ray Robinson," Brook told BBC radio 5 live ahead of this fight. "When you talk about boxing you talk about them. When you talk British fighters, Benn, Eubank, Bruno, I want to leave this sport an old man and still have people mention the fights I've been involved with. So when you speak about boxing,. you speak about Kell Brook."
Who knows what the future holds for Sheffield's latest fight star? It looks like he has every chance of reaching the stars.

Kell Brook says his leg feels fine and adds "I'm back baby!"
And a message to Amir Khan: "If you're watching, come on, get in here with me. The best is yet to come. Believe it."
The champion high-fives his promoter Eddie Hearn. They are spinning this big time, no secret Hearn wants another Wembley mega-card on 13 June.
And we are about to hear from the champion...
Kell Brook has 34 wins from 34 fights and his latest is impressive to say the least.
Just the four knockdowns in 12 minutes. He was controlled, thoughtful, artistic.
It was as if Jo Jo Dan's corner were watching replays on the big screen of the destruction coming their man's way. A left-hook right on the bell in the fourth round delivered some serious pain.
It's a left hand to the side of the head as Dan held a low position. It came down on his temple like a missile dropping from on high. Throw in the fact the travelling fighter was off balance and there was only one way he was going. Down.
Brook is ecstatic, on the ropes, slapping his chest with a grin.
