Football historian Mikel Arteta has been teaching his Arsenal players about the legendary exploits of today's FA Cup opponents Nottingham Forest and their mercurial former manager Brian Clough.
Arteta, 39, was not even born when Clough's all conquering side succumbed to a Frank Stapleton goal as Arsenal won an epic clash at the City ground before going on to lift the trophy in 1979.
Forest were unbeaten at home all season, league champions and European Cup holder too as Clough worked miracles to make them the best against all the odds.
