I don't recall back then there being another quality striker to push Heskey for that 2nd forward role so people just had to accept it.
Now we seem to have a glut of young talent who are quite obviously much better than Welbeck hence the outcry.
My think there were plenty of English stikers with better goals game ratios than Heskey, but they belayed for clubs smaller than Liverpool and were ignored back then.
If we didn't take Welbeck to WC, which other striker would have gone?
he shouldn't start if that most if us agree, but if we need to bring a striker on with pace. He's our only spare option.
