Olivier Giroud is struggling with that knock he got in the first half and now accepts he cannot continue. He is replaced by Alex Oxlade-Chamberlain and Giroud's foot immediately receives some treatment from the Arsenal medical staff. Gunners fans will be hoping that is nothing too serious...

Almost a third for Marko Arnautovic as his shot beats Vito Mannone but trickles just beyond the far post.

...breathe easy, Watford fans, looks like Heurelho Gomes is good to continue, although Sebastian Prodl has to take his goal kick.

Concern for Watford. Heurelho Gomes is down on the ground and looks to be in some pain after a colliding with a Middlesbrough player in the box. Sub keeper Costel Pantilimon is warming up...

Burnley and Southampton are winning the race to be last on Match of the Day tonight.

That's all you need to know.

Eddie Howe is not here to put boots on caterpillars.

With his side chucking away their one-goal lead he brings on Callum Wilson and Joshua King and takes off Benik Afobe and Ryan Fraser.

Ryan Mason has a decent effort for Hull, hitting a rising effort just wide.

You could say it was bad luck for Swansea - Iwobi shoots from such an acute angle.

But I'm not sure it was on target, it looks like a Jack Cork own goal. It's rotten luck for Swansea but a huge result for Arsenal if they can hang on.

This is an incredibly tough job for Paul Clement.

Andy Carroll does almost everything right here. He takes down Mark Noble's free-kick on his chest, fakes to shoot with his right but drags it on to his left and clips a shot past the near post.

Swansea are on the ropes with Arsenal having started the second half strongly. 

Alex Iwobi has a shot blocked before Alexis Sanchez's brilliant pass puts Aaron Ramsey through, but his shot is denied by Lukasz Fabianski from close range.

You know what would make things interesting? An early Sunderland goal, and that almost arrives as Fabio Borini powers a header at goal but Lee Grant does well to parry the effort away.

Moments later, Charlie Adam flashes a free-kick just wide. There's more goals in this game.

Yohan Cabaye fancies a long-range sizzler today for Palace. Christian Benteke heads it down for the midfielder who lashes a dipping half-volley just over.

The Hammers have made a change, meanwhile. Sam Byram is on for Angelo Ogbonna, meaning Slaven Bilic has abandoned three at the back for a flat defensive four.

Chance for Watford straight off the bat as George Friend misjudges his header and ends up almost assisting Christian Kabasele, but the Watford man nods wide.

All six games are now go go go for red-hot, second-half action.

We're back under way everywhere, bar Burnley and Sunderland...

Pep talk from Granit Xhaka in the tunnel before the Arsenal players head out. "First 15 minutes are important guys, come on," he shouts and out they go.

Olivier Giroud looked like he wanted to go off after scoring - he took a knock to his ankle earlier - but he is back out for the second half.

The 31st edition of the Africa Cup of Nations will kick off in just under five minutes as hosts Gabon take on debutants Guinea-Bissau.

Sixty years have passed since the first Nations Cup, which took place in Sudan in 1957, consisted of only three teams and was won by Egypt.

This year's edition has 32 matches over 23 days, featuring 16 teams - who begin their quest in four groups of four - and will end on 5 February with the winning finalists lifting the Italian-made trophy and taking home $4m (£3.28m).

You can follow all the action here.
