Teemu has been always the kind of striker who needs correct kind of balls to score goals. Since Emi left no such balls around regularly. But if you watch the ball from Gibson in the Luton match you always knew that Teemu is going to score with that backspin shot, before he took the first touch.
But if Norwich has a plan like yesterday where most of the balls are crosses, everyone knows that you don't do a **** with Pukki. So if that's the masterplan of mr. Wagner, maybe selling Pukki at this point would be decent for everyone. And still, even Pukki has not been in the full form, he is #2 in scored goals and #1 in assists what it comes to Norwich. In the end of the season he is most likely both the best goal scorer and giving most assists.
