Not sure why you mention the 1970s.
It was important then as it is now to have a good keeper.
I believe a good keeper is as important as a good striker. The difference between our opinions is one of priority.
The top teams in every league right down to the Western league have a good keeper, the best available.
Look at the Premier League, you're more aware of these keeper's at Man City, Liverpool, Villa, Newcastle etc but my opinion, I believe, to be proved is what Arteta did at Arsenal. He got rid of an England keeper to bring in Raya.
Ps I get the squad depth needs increasing but our priority is a better keeper and striker.
Pps the '1970’s'......again my point of a good keeper......the best outfield players never to win the European Cup were Leeds Utd who had a suspect keeper Gary Sprake.
