Top of the pile is a link to a debate in a national newspaper. “Jordan ­Henderson: the worst £20million buy of all time?”

And it goes on. Criticism and gags — and that is just on Liverpool forums.

Even more than Andy Carroll, even more than Stewart Downing, ­Henderson became a ­symbol of what was ­perceived to be the ­expensive failings of the previous Anfield ­regime.

Whether Carroll DID what he was supposed to do was doubtful. But ­at least everyone knew what he was ­supposed to do.

Everyone knew what Downing — a quietly ­effective performer here — was supposed to do too.

But a refrain ­became ­familiar around ­Anfield. What exactly does Jordan Henderson do? Here was stirring ­evidence of what Jordan Henderson can do.

There have been ­fleeting signs of quality in his time at Anfield but this was a dynamic, aggressive ­display — consistent for 77 minutes on the pitch.

He has never been a dud, Henderson. You don’t play for England at virtually every level, and then make the transition to the ­seniors, without ­serious talent.

Managers with the ­experience of Fabio Capello and Roy Hodgson do not show faith in you without good reason.

But it is fair to say his impact for Liverpool has been limited. The reasons are mixed. There is little doubt the price tag was a factor. Not so much the proverbial burden, but a number he tried too hard to live up to.

And too often, he was deployed wide — clearly not a position that suited him. Yesterday — and this is to Brendan Rodgers’ credit — he had what has to be termed a free role (until moving into a more fixed central area after Lucas was withdrawn).

And he revelled in it, revelled in the more ­attacking nature of his brief. It was not just the succulent strike which kicked off this romp that caught the eye — it was his effervescence, directness and intelligence.

OK, it was against a ­Norwich team that ­performed lethargically and that defended ­catastrophically. That is a caveat which must be ­remembered when lauding the contributions of Luis ­Suarez, ­Steven ­Gerrard and ­Daniel Sturridge to this victory.

As Gerrard says ­elsewhere on these pages, these sorts of ­performances are fine and the general direction under Rodgers is ­positive.

But Liverpool need to find a greater ­consistency. Yet you can only perform against what is presented in front of you. And ­Henderson ­deserved ­every moment of the ­rapturous applause that marked his ­substitution with a quarter of an hour remaining.

Henderson still has a long way to go to get the critics off his back but, at 22, he has plenty of time to do it.

And a standing ovation for the worst £20m buy of all time is not a bad start.
