As excitement builds in England in the run-up to the country's first World Cup semi-final for 28 years, midfielder Dele Alli insists Gareth Southgate's team are keeping a cool head in their tournament "bubble".

"You are in your own little bubble when here — training camp, coming back, getting ready for the next game. It is not until you look at social media and the internet that you realise how big it is," Alli said.
