It's desperation stakes for Burnley so they have rolled the dice. I can't criticise them - it might just work. They have nothing left to lose, so a deseprate punt as a last resort is them pressing the nuclear option. This could have been us had we lost to United. I wouldn't have argued against it.
We have simply got to keep focused on our task at hand: that is beat Leicester. Every win drives the stake further into Burnley's heart. If West Ham can keep their own focus, it'll be hard for Burnley to win there. Either way, Leicester is huge for us. Time to drive on now.
