I wasn't around when Forest won the league and European Cup twice but I have read snippets in books etc... but wasn't Shilton relegated with Stoke before he went to Forest? Albeit being in an inexperienced an young side. Also I am pretty sure Robertson was on the transfer list when Clough arrived at Forest.
Francis didn't arrive until 79 as well, almost a year after the title win.
Either way I don't think it would be as big as an achievement as the Forest title win as they did it as second division champions although if Leicester do win the league I reckon it would come pretty close.
What seperates Clough's Forest is the two European Cup win and winning the league coming straight from the second division
I obviously want City to win the league but a part of me wants to see Leiecester do it because I just think it would give the whole Premier League an incentive to believe in the almost impossible and hopefully making the whole division more mentally stronger and competitive.
