Err, no it isn't, how do you work that out!?
Smith and Kuyt are both similar, they are not penalty box strikers, more like forwards who operate outside of the box using their stamina, work rate and battling skills to harass the opposition and to toil away for their more skilled team-mates, while chipping in with a few goals and efforts at goal themselves. Play Smith up top in a run of games and you'd get pretty much the same out of him as Liverpool do with Kuyt.
Ashton and Shearer though? The similarities end in their nationality as individuals. Ashton is more akin to Viduka than anyone else, especially Shearer.
Smith isn't in the same league as kuyt skill wise. He's been a major factor in their good start this season.
Skill-wise? Kuyt's hardly fucking Rivaldo. I'm with the coach: can't see that much difference between Smith and Kuyt, tbh. Kuyt probably a better finisher but I don't particularly rate either of them.
