• See here for Group 1 and Group 2

This group included the holders as well as the eventual winners, with their game memorable for a save regarded as one of the best of all-time.

England 1 Romania 0

England had played Ecuador (yellow shirts with a blue sash) in a pre-tournament friendly and, with his yellow and blue tops unavailable, Gordon Banks had worn his red long-sleeved training jersey, with England crest and, according to Simon Shakeshaft, possibly number 3 (his training number) on the back.

However, for this game he was in his usual yellow for the first half and, when the confusion between him and the Romanian team was flagged, he wore a plain red t-shirt in the second half – perhaps the first professional goalkeeper to wear short sleeves?

Brazil 4 Czechoslovakia 1

Brazil had two sets of shirts, one made by Umbro and one by local supplier Athleta, but they were pretty much identical.

The goalkeeper jerseys did have differences in terms of the ‘Brasil’ script – we’d imagine Félix to be in the Athleta version here and it was the only one he wore in the group stages.

Czechoslovakia had an all-white kit but changed to blue socks here due to the clash.

Romania 2 Czechoslovakia 1

Having worn plain blue shorts against England, Romania had a set featuring three white stripes here – presumably adidas but possibly Le Coq Sportif.

Goalkeepers Stere Amadache of Romania and the Czechs’ Alexander Vencel were in outfits which were identical apart from their respective countries’ coats of arms – clearly they weren’t too worried about the Mexican heat.

England 0 Brazil 1

Until a few years ago, I had thought this was a shorts- and socks-clash with a “We’ll change one and you change the other” solution, like Chelsea v Luton in the 1994 FA Cup semi-final.

However, England had taken the decision to go all-white due to the heat (the shirts and shorts were Airtex too), so Brazil’s socks were the only change from the tournament defaults – quite why they chose grey is anyone’s guess.

According to the excellent England Football Online site, Gordon Banks switched from yellow to blue only five times between 1965 and 1970, but this save means the back-up shirt is remembered.

Brazil 3 Romania 2

The final round of games brought two direct colour-clashes, with Romania going with light blue shirts and white shorts. Their goalkeeper Stere Adamache had to retire injured in the first half, with his replacement Răducanu Necula wearing the blue shorts and red socks from the home kit.

Czechoslovakia 0 England 1

England opted for light blue rather than red as a second choice, with the crest unusually not on a white background (nor was it on the GK shirt).

However, viewers on black-and-white television were left confused by this match-up, with the result that England reverted to their more familiar back-up colour for the knockout stages.
