I think Vic offers a lot more than the likes of Zamora, Cole, Di Santo, Jerome, Welbeck, Defoe, and Agbonlahor ect. and still has potential to polish up his game. Outside Man U/City Chelsea and Arsenal Vic would be the second choice striker or 1st choice for the bottom half of the league.
The main things Vic lacks in imo is self-belief and attitude at times (fans partly to blame). Footballing wise he doesn't try hard enough but this could be put down to fitness and lack of match sharpness as the last time he had a run in the team he looked a force (before the Nolan tackle). Other than that all that pisses me off is his pee rollers across the box, but that can easily be worked on in training and not a major attribute for a striker anyway.
