Clearly this is not the Grant Holt who scored 15 Premier League goals last season. But it's important not to panic yet and assume that Holt is past his best.
It's a natural human reaction to remember things better in the past than they actually were. Holt has always been a slow starter. This is why people accused him of not being good enough for the Championship or Premier League in previous seasons.
Last season, this is the reason that he found himself having to battle back from the bench to prove he was worthy of a starting spot. I think Holt enjoys being criticized, because he loves to go out there and prove people wrong.
Norwich City manager Chris Hughton must decide what the right treatment for Holt is. Clearly, he has the option of sticking by him, or to bench him for the next couple of games. Nevertheless, whatever he decides, I am confident Holt will prove he is every bit the player he was last season.
