Purely based on stats didn't our front 3 score more than your front 3?
Bet you your three scored a way higher total percentage of your goals this season than ours, which suggests an over reliance on them. I'd also be surprised if our boys didn't assist more than yours as well, not sure on the stats for that. Assume goals scored stat would include the Europa League games against less than stellar opposition, although ultimately all goals count whoever they're scored against.
I think if you delved deeper into those stats and their implications, it would certainly lend itself to the argument you need more reinforcements other than in attack. As good as Sancho is - fee aside, I think he's going to be highly effective and a real quality player - is he really what you need to spend that amount of money on? Inclined to agree with KK that 120m could buy you several defenders which you desperately need. If you end up with them as well as Sancho, well that would give you something to be happy about.
