You are right, Nigel Clough did play for Liverpool, but I appear to have no memory of it.
I liked Brian Clough, another one for the neutrals, to drag a club like Forest into winning the European Cup.
I think it was Forest that were also cheated by match fixing and a bent referee, only to be admitted some decades later. Can't remember who the cheating team were, my brain is saying Athletico, but think that's wrong. Either that or the whole thing was a false memory.
Only gripe I had with Cloughie was spending a £1M on Trevor Francis, which opened the door for silly money transfers, albeit some might argue Clough would never of won the EC without him (Francis).
