That's a stretch, I'd say (if I can butt in). The problem is that no English fan has seen Beckenbauer anything like the number of times they got to see Moore. So it's difficult to compare them fairly. Probably the best English defender ever.
Moore def renowned as best english centre half ever ,but Colin Bell led him a merry dance at the Boleyn ground in our 4nil win 69/70 season I think.
Moore was asked to msn mark Bell and he dragged him out of posistion all over the pitch,made him look a carthorse.
As far as best English defender is concerned I always felt Kevin Beattie at Ipswich,when fit,was a close 2nd to Moore rugged tough defender but very skilful too and would often carry the ball stylishly out of defence and could play long accurate 70 yard balls.... ,and score goals,something Moore wasn't renowned for..
Back on topic, the Oldham defeat August bank holiday ,under Keegan,iirc 1-4 was hard to take, no one on the Kippax that day would have believed we'd go up after that beating...but we did.
Roger Palmer and a certain Ricky Holden did the damage that day
Holden slung in high arching crosses from the left to the back post where Palmer rose like a salmon to head in. Palmer hat trick.
I was at the Maine rd arsenal defeat and remember clapping them off half time and full, they were different class....and went easy on us after 20 mins,thankfully. 1- 5 ,butcoukd have been so much worse.
