"DeGale's face is getting ever more reddened. Both fighters are landing solidly, but also missing at times."

Time for DeGale to step it up again, his trainer Jim McDonnell certainly thinks so. Dirrell finds the target with a big left, the American pouring it on now. DeGale not doing enough again, Dirrell looking the more dominant force in there now. Nice jab from DeGale, Dirrell lands with a flashing left just before the bell. That's Dirrell's round again, I've got it level - but the three judges might disagree...

"The perception was that Dirrell was controlling the round. DeGale was not able to find his distance very well."

DeGale not doing enough in the early stages of the round again. Dirrell lets his hands go but most of those punches were blocked. DeGale talking to Dirrell now, taunting him. Got to be careful with that overhand left, though. DeGale has given that round away, though, Dirrell has simply outworked him. This could be getting close.

BBC scorecard: Dirrell 65-66 DeGale

Barnaby Chesterman: I might be a touch biased but for me DeGale landing more, cleaner and harder punches. Hard to give any round to Dirrell.

Tom Haddigan: I still take James DeGale to win as Dirrell gets discouraged.

Alex Day: Funnily enough Dirrell doesn't seem so keen on the trash talk since round 2.

"DeGale landed the harder shots and the more action there is, the better for him. Dirrell has blood coming from his nose and the inside of his mouth."

Let's hope DeGale hasn't gassed early - he's started the sixth with more intent. Dirrell backs him onto the ropes but DeGale finds him with a left-right combination. Smart left from Dirrell, before DeGale pins him in the corner and lands with a clubbing right. It all goes off in the final seconds of the round, with both men landing with big shots on the bell. Tight one, but maybe Dirrell's again.

Good, flashing right hand from Dirrell at the start of the fifth. DeGale lunging in and he gets clocked by a left hand. DeGale suddenly looked tired in that round, too many single shots, making it too easy for Dirrell to counter him. The American surely closes the gap.

James Peacock: Great fight between DeGale and Dirrell. Awesome stuff.

"There were some mind games at the beginning of the round - a battle for real estate as they kept changing stances, but Dirrell kept landing his jabs."

The cut above DeGale's right eye is not much more than a nick, so no real drama there. Dirrell turns orthodox at the start of the fourth, trying to get that left jab in DeGale's face. DeGale switches as well and it's all gone cagey... Dirrell chatting to the ref and DeGale makes hay, clocking him with a right jab. We've suddenly got two southpaws again, big swing and a miss from DeGale, needs to be careful and keep his shape. I'll give that one to Dirrell courtesy of some nice work with the jab.

BBC scorecard: Dirrell 35-39 DeGale

"Dirrell seemed to control a lot of it in the first two minutes in the third round, but then DeGale took control. Dirrell needs to get back to his basics and keep it simple, If he gets too complicated, DeGale will pounce."

Dirrell looks to have recovered well enough by the start of the third. Big left from Dirrell, back of the neck, this is warming up nicely - what was that I said about two southpaws equalling a stinker? Not a bit of it so far. DeGale lands with another left as Dirrell jags his head back and that's surely enough for DeGale to nick it.

"DeGale landed a brilliant overhand left with 15 seconds to go. He was cut, he was under pressure, but what a response. He's turned the fight his way."

Plenty of chat at the end of the first, with both men giving it bunches. I think it's safe to say these two men don't like each other much. Smart jab by DeGale but Dirrell fires back with a whiplash cross. Looks like DeGale's got a cut right eye, he's pawing at it. Good combination from Dirrell as DeGale suddenly looks rattled. Dirrell flattened by a huge left hand! What a shot with 20 seconds left in the round. Dirrell gets a standing count after touching down again and DeGale goes in for the kill. Dirrell, on rubber legs, saved by the bell...

Derek Rivers: James DeGale all day, finish stronger, comfortable points win.
