True, but to counter.
Firstly – there was a time when we undoubtedly led the world. Banks, Shilton, Clemence, Jennings (OK Irish but a product of the english league) and so on. Inevitably as time passed other nations caught up, more exposure and more to pick from and so english GK stand out less. There are still plenty of good ones, Butland, Foster, Forster, Hart.
Second the game has changed. GK now have to be able to play with their feet, where in the past – a backpass? Pick it up. That is a wholly different skillset and some of the worst errors come from that aspect. But also the ball. I didn’t play in the era of heavy casers, but of the Mitre Multiplex. But for fun a while back we were at a barbecue and the teenagers there had one of Nike PL balls, and the bloody thing swerved all over as well as flying further and faster.
In fact just about the only thing I’d like nowadays about the game compared to ‘my’ era of the late 80’s and early 90’s is that goalmouths now have grass in them. In my day the option was either baked earth (early and late season) being replaced by knee deep puddles and / or a beach of jagged sharp sand (the rest). With occasionally the mud being frozen into ankle wrecking ruts (January/February, but the ref’s ruled that the centre circle will take a moulded so get on with it)
