Caballero for me. Saved the penalty which I think swung the match in our favour. He also made an unbelievable save near the end with his right foot which would have given them the incentive to go on and qualify. After Falcao's second, I saw him run over to John Stones (who's mistake let Falcao through), he picked him up and you could hear him revving him up and getting his head back into it! It shows what a leader he is - I'd argue that his pep talk could have been instrumental in giving John that motivation to get forward and bag our fourth!
He's becoming the biggest cult hero in this team with these performances!
