for a start, you are forgetting about Macheda...but more to the point, i have to disagree here...
its been proven you need 4 top strikers to compete on all levels.
while young can backup as a supporting striker, he is no out and out striker.
whats more important is that we lack a big strong striking threat, something that is different to what we have to offer.
we havent had a threat like this since RVN
id like it if we were to go after a striker in the Llorente mould (assuming we do let go of the excess strikers, financing this should not be too difficult)
