The following month, Ayris started in Bobby Moore's testimonial, scoring West Ham's second goal in a 3–3 draw against Scottish champions Celtic.
Hospital tests the following day confirmed Ayris had developed an air bubble on his lung.

Ayris' only goal for the side came in the 1971 UEFA European Under-18 Championship final in a 3–0 win against Portugal.
