He looks fun in the pre inter videos. Obviously he looks good but I've no idea how he fits unless you put him at 10. He doesn't pull away with pace he has to keep turning to create space for himself. A short guy up top that's not rapid like Sanchez was, could be a disadvantage to the team.
When you spend that kind of money you expect a signing that takes the team up a level. This guy looks like he's had his break out season and he has the same combined goals and assists as Mkhitaryan this season. And that's with the team adapted to him he has Lukaku as a battering the CBs in front and scaring them with his pace and strength so he can just drift into the space that makes. If he can here he be battered by prem CBs and he would have to do the work Lukaku does.
If he was at a smaller club and the price was 20m I'd understand it. But £70m just seems very over priced. That's Sancho money who got 20 goals and assists last season. And can play all across the front and is only 20.
