Wonderful photo, this:

Sometimes it’s easy to forget that it wasn’t just England and West Germany at the 1966 World Cup. Here, Brazil’s goalkeeper, Gilmar, leaping to block a shot during practice in Liverpool. First off, isn’t it amazing how low-key and open the training session is - totally like the shut-off camps in Rustenberg and the like today. The keeper’s prodigious leap is caught perfectly, but it’s also given a great contrast with the grey mud on his shorts and schoolboy in shorts looking on in wonder - he might be Brazilian but this is very much an English photograph.
