If Wales' Harry Wilson finds himself staring down the goalkeeper and in a position to score a legendary goal for his country tonight, it will be the 'Rushie Challenge' that has prepared him to make the best of it.
Ian Rush's objective when he coached Wilson at Liverpool's Academy and in the under-15s Wales set-up was to make him two-footed. He'd ask him to stand with his back to goal, exchanging passes with him, then suddenly playing a ball past him, asking him to wheel around after it and shoot with either foot.
'I can pass it to his right or left - he doesn't know when or where I'm going to send it,' Rush says.
