He was knocked out the moment he decided to kick Schuster out of the side, a CB would have helped immensely.
Also glad to see Voronin progressing to the semis here. He's not the flashiest name around but going by his tournament performances (as we have to for a fair bit of 50s and 60s vintages - Brazil 58/62, Masopust, Dzajic, Yashin and the likes), he was just immense. His man-marking display against Eusebio was honestly the best that I've seen, whilst his other performances were quite impressive too. I'll hold my hands up and say I've been guilty of underrating him too. I've watched him against Spain in the 1964 final (where he was Soviet's best player) and some footage here and there but not enough to form a comprehensive appraisal of him (not that a handful of full match footage is enough but yeah, goes with the territory).
Sometimes the player whom the man-marker is man-marking can be out of form, making the man-marker look better than he is. But when the player does it twice, consecutively, and against two of the most in form forwards (scratch that, players) of the tournament - Albert & Eusebio, it really means something. Esp Albert, whose performance compilations for every match is available, as too is Eusebio's (except the one against Soviet but it's understandable why it wasn't made
). Really shows the impact that Voronin has on them, and also how the man-marking is clean it is, with barely any dirty blocks or fouls, although he could get physical if needed be. Yet to see such pure and clean man-marking displays elsewhere.
Also another key aspect about it, was that it was very much single-handedly done without much support. If you watch Stiles man-marking Eusebio, he frequently had the support of Moore who was playing as a covering safety net behind if Eusebio slipped through and Eusebio was frequently double/tripled upon by opposition throughout the tournament. However, whilst Voronin could rely on the support of his teammates occasionally, it was almost as though he was exclusively handed down the responsibility of looking after Eusebio and Albert which just shows the amount of confidence they had in his ability and how good he was defensively. That's not to downplay his Soviet teammates who played really well and were a fine side overall, who deserved more recognition. I'd seriously recommend people to watch those matches in full for themselves, as there's only so much a compilation video can cover.
