"You can only give credit to him for moving countries, coming to a new club and playing the way he's played straight away," Stones said. "He's been outstanding and that's just down to him. It's a massive credit to him.
"We try and chip in and everyone's out there working hard. Sometimes it doesn't come off for the striker but today me and Ruben chipped in. That's part of us being such a good team, and such a collective in big games.
