Some serious questions have been asked of Onana, with costly errors blighting Premier League and Champions League performances, but Ten Hag has said of his last line of defence: “If you analyse it well then you see he is the second-best goalkeeper in the Premier League based on stats, his expected preventing goals is second-best in the Premier League. He's doing well but he knows that in the Champions League he has made some mistakes but all over in the first five months he has done well. You know also. Because you have seen how he is reacting on a bad performance like in Munich at Burnley he was outstanding. He is a strong character, he is a personality and he will deal with it.”
