I'm happy with Krishna, he is quick and has good composure. As many others have mentioned, I don't know if we could have done better at this time. It would be nice to see Krishna score plenty of goals but I'd also be happy if his touches are good, he passes well, beats the offside trap and works hard off the ball. We can't expect an ASB player to be scoring off the get go but a work rate like Reira would be nice.
Merrick has already proven he can get a lot out of players. Reira is quickly becoming my favourite Nix player. His work rate and passion is at times intense and he is improving almost daily. He already bosses the midfield effectively and I believe his best is still yet to come.
Bring on Krishna!
edit:
I'd like to see a formation like this:
4-2-3-1 with Krishna up front and Stein, Hernandez and Boyd behind him. I think that would make for exciting football.
