Fierce rivals Nottingham Forest and Derby County will put their differences aside this weekend as they both mark the ten year anniversary of their former manager Brian Clough.
Considered one of the greatest English managers of all time, Clough led both sides to the Division One title in the 1970's.
Clough was first in charge of Derby between 1967-1973, during which time he took the from the second Division to Division One champions for the first time in their club's history, as well as reaching the semi finals of the European Cup.
He left Derby after falling out with the club's board, and after spells at Brighton, and his notoriously ill fated 44 day stint at Leeds United, he became Nottingham Forest manager in 1975.
He went on to manage the club for 18 years, in which time he won the Division One title as wells winning the European Cup twice in a row. He retired from football in 1993, and has been regarded as a legend by both teams for leading them to their first respective Division One titles.
He died of cancer on September 20th 2004, and with the two sides meeting less than a week before the tenth anniversary of his death, the rivalry will for now be put to one side, as they both honour him.
On the tenth minute of the match both sets of fans will give a standing ovation as a mark of respect to the man dubbed 'the greatest manager England never had'.
Neither clubs have reached the heights of their respective eras under Clough since he left, with Forest relegated the very season he retired, in the inaugural Premier League season.
