I have a feeling Wenger will have looked at the two and decided that he already has a similar(ish) skill set in a forward in Welbeck. I'm only going off stats on shitty old
Squawka here, but if they're accurate then there doesn't look to be a whole lot in it per 90 minutes - not £50m+ worth of difference anyway...
Giroud - Welbeck - Lukaku stats >
By far the biggest thing that Lukaku has in his favour there is that very first stat: he's been available for over 3000 minutes of football whereas Welbeck has barely clocked 500! But it doesn't really matter much how we read it - the important thing here is how Wenger will see it, and I can already hear him saying "I already have Danny Welbeck - what would I do with them all when he's fit?"
