However any glance at the sartorial elegance or otherwise of the participants in the Chelsea dug-out would have suggested that Chelsea's revolution has already taken place in the managerment hierarchy.
Avril Grant is either first team coach or manager depending on official club sources. This is reflected in him either wearing a suit (manager) or nice, warm quilted jacket (first team coach).
Now, Chelsea have two first team assistants in Steve Clarke and new boy on the block Henk ten Cate.
If anyone was in doubt as to who was more in charge let there be no more discussion.
Ten Cate was decked out in an immaculate suit, whilst long-serving Clarke was decked out in traditional training garb.
Clarke even took the pre-match warm-up for the players, which one ex-pro described to me as the "lowest of the low jobs" .
Clarke has fallen down the pecking order and he knows it.
Ten Cate was jumping up and down to get his message across to the players while Clarke sat imobile until called upon to organise the subsitutions with the fourth official - doing the donkey work like an old fashioned water carrier.
Still, Clarke will no doubt have a laugh as much as the rest of us who saw it when Ten Cate comically fell backwards over water bottles into the dugout and fell into the other acolytes in the dugout.
