Him & Kopa only briefly crossed paths on the park in Poland, from what I can see. One match Sheridan played 90 mins, Kopa came on in injury time, finishing 0-0. Other match, Kopa played 90 mins, Sheridan came on 62nd minute, with Sheridan's team scoring only goal of the match with a few minutes to go.
It took me a while to figure out Rudan's tactics: to have enough players on the park who can understand Polish cursing when Kurto starts swearing at them from behind. Kopa is a native speaker, Sheridan had two seasons in the less-than-cosmopolitan Polish provincial city of Bialystok so he picked up lots already. And even Taylor is bound to understand some Polish cursing (assuming he ever needed plumbing work done on his house in UK).
