There's been a couple of moments in the games I've seen so far where not many other strikers in the world have he technical ability and intelligence to pull off. The way he was recognising where the pockets of space to drop into against Dortmund, receive the ball, use his footwork and a couple of quick steps to keep possession under pressure, and then have the iq to slide a perfectly weighted through ball for a team mate... We know he's going to score goals - his movement and finishing always show that - but you add on top the creativity he has and that's a £60-70m player right there. I don't know how we let that go for the price we'd probably get for him (£20m max, I assume).
I think I'm at the point where I ignore the wages, ignore the fact he can go for free at the end of the season, and I hope we can get 10-15 starts out of him when we absolutely need it. He's too good. Also, he is probably the most fun player watch in the squad - from a selfish perspective I'd love one more year of watching him making defenders look like idiots.
