I think the problem with all of our strikers is that none of them are good from the start!they all seem best as impact subs!Saha's goal came when he was a sub and came on against Fulham. Denis was poor when he started against Bolton but had an impact on the Norwich, West Brom and Wigan games as a sub, likewise Vellios looked good when he came on against Villa and scored as a sub against Wigan, Bolton and Chelsea. Solution for me would be to start Vic against Blackburn if he has it in him, as his confidence seems the highest currently and seems the freshest, then make the changes if it's not going right, knowing that our other strikers seem to make a better impact coming off the bench.
I do think the subs should be made earlier though. Unless a sub is brought on to waste time, I don't know why they wouldn't be given at least 15 mins. Denis came on for Saha with about 3 minutes left on Saturday when I thought we could have really gone for the win after vics goal.
