Scotland head coach Andy Robinson has lit the blue touch paper ahead of his side's RBS 6 Nations opener with England.
Robinson's Scotland take on England for the Calcutta Cup in the opening round of Six Nations action on February 4.
The former Lion has put the boot into his fellow countrymen and reckons England's controversial World Cup was due to their arrogance.
"It's important for any team to show humility, especially when you are winning," Robinson said in the Mail on Sunday.
"I thought a number of the England players undermined this in the arrogance they showed. They know who they are and it was not across the board, but, unfortunately, the whole squad got tarnished.
"You need self-belief in players, of course, but you also need to possess some humility, and a number of players overstepped the mark."
Robinson, who spent several years coaching Johnson in the English set-up, has plenty of sympathy for the former manager. But he expects a back-lash from Stuart Lancaster's new-look England.
"What surprises me about England now is that they fell into a downward spiral while winning. It wasn't results that undermined them but the other stuff. They self-destructed.
"But the players will be coming here with all that's happened in their armoury. All the blood-letting, all the resignations and sackings, all the criticism.
"They are a good side. With the resources England have, they are never a bad side, and while people refer to their inexperience, most of the team who beat us in Auckland then lost to France in the quarter-final will be on that pitch.
"More than anything else, more than it's us and it's the Calcutta Cup, they each have a big, big point to prove."
But Robinson insists Scotland also have their own scores to settle after their own disappointing World Cup campaign which ended at the pool stages and included a defeat at the hands of England.
"I genuinely believed we were going to win the pool, and we got ourselves into positions to do just that," added Robinson.
"In fact, I believed we would reach the semi-final stage. Ultimately, we under-achieved. The feelings of 'if only' and 'what if' are the worst in the world.
"It is not a false belief when I say we're good enough to beat every team in the Six Nations. I've had enough talking about potential. This time we must deliver. It starts against England."
