Enough of technical ability but lazy to execute it on the pitch like Martial and Rashford, it’s perhaps time we have these qualities in abundance in a striker. Ruud has all those similar qualities and he was brilliant
I haven't seen him play live, but from what I've seen from him via highlights, his touch and technique looks fine.
And like you've pointed out already, we've got Martial as the technical profile and need something different imo. And it looks like Nunez provides that something different through relentless work rate/intensity, movement, physicality and a aerial threat.
And as far as possession play is concerned within the positional play principles. The deeper you're in the build up phase, the better you need to be on the ball. So the GK, defenders, midfielders, fullbacks, inside forwards will need to be good on the ball imo.
And when the build-up play improves to a high level, the team requires a killer in-front of goal who has the ability to run in behind, hold up play, run the channels, press the opponent and provide a direct vertical option along with a aerial threat. And Nunez seems to be someone who is going to provide that.
He's still young and will improve further but he's a similar profile of player to Didier Drogba and Diego Costa.
