The two that stood out were Alfie Conn, as mentioned, and Steve Perryman. Perryman looked busy, had time on the ball, never wasted a pass. I suspect he was a player that I didn't appreciate during his career, I was too young, but you Spurs fans will know all about him.
It was really enjoyable to watch. I thought the game would be very dated, the players look pedestrian and poor. In fact they were excellent, it was more rushed than possession based but it brought back great memories for me of a style of football that I grew up with and thoroughly enjoyed. I'll be looking out for more of these.
