Martinez broke French hearts once again as he made two saves during Aston Villa's penalty shootout against Lille. The Argentine saved Lille's first penalty taken by Nabil Bentaleb and immediately turned to the fans in a mocking fashion. Then, while stood off to the side watching Ollie Watkins prepare to take a spot-kick, he appeared to motion to fans, and his actions saw referee Ivan Kruzliak show him a yellow card, his second of the night after he was shown one in the first half for time wasting. Despite the second booking, Martinez was allowed to stay on as he saved another penalty to lead Unai Emery's side to the semi-finals of the Europa Conference League.
