It's an often trodden out line: 'If Lionel Messi had done that we would be raving about it.'
But it isn't frequently used to describe Olivier Giroud.
That is exactly what Paul Merson did when discussing an outrageous piece of skill from Olivier Giroud for his second goal.
The ex-Arsenal man told Sky Sports: "If Lionel Messi done that, we'd be going mad. That was absolutely phenomenal."
And he's right, the skill was superb, and a game-turner, with Merson going onto describe it as 'Bergkamp-esque'.
Merson later added however.
"I watched Lionel Messi the other day against Atletico Madrid. I wouldn't have paid £2m for him."
Perhaps that explains it.
