Thomas Tuchel gambled one last time. He played the joker, the goalkeeper whose refusal to stand down for a penalty shoot-out had come to define his Chelsea career. He brought on Kepa Arrizabalaga.
There was a minute to go in extra time. Edouard Mendy had not put a foot wrong. Clearly, Tuchel fancied his understudy more in a showdown. It was a bold move. Had Chelsea lost Tuchel would have been accused of undermining his number one, of risking unnecessarily. He did not lose. Chelsea won 6-5. Arrizabalaga made two saves, including the last one, from captain Raul Albiol.
