Hart was left helpless twice late in the game as Griffiths thumped in two memorable free-kicks for his first goals for his country at the 13th attempt.
And the shotstopper reckoned he’d have needed five Peter Crouches in his wall to stop the Scots frontman.
He said: “As a goalkeeper, you set your wall up and sometimes there’s nothing you can do. He’s produced two bits of quality.
“To do it twice in a few minutes after not really having a sniff the whole game was a big moment for him.
“It was unfortunate for us, but we saw four minutes on the board and thought we could get a goal – and that’s what we did.
“I spoke to him privately after the game about the previous match we played at Wembley.
“I’m prepared for anything and at the end of the day it’s a free shot from 25 yards. We train every day, but unfortunately it was his training that paid off.
“I’ve seen it again and we would have needed four or five Crouches in that wall to make a difference.
“Of course, we studied his free-kicks beforehand, but you have to say well done sometimes.”
