I wouldn't even take him for 20m. He is just not the player we need and not good enough. Another player like Griezmann, Dembele, Coutinho, Messi, Suarez who wants the ball at the feet and is "good at building up". But who will all of these players eventually build up play to? Who will run for their passes?
I promise you within a month or two with this guy here he will be regarded as Griezmann, Dembele and Coutinho.
Poor man's Gabriel Jesus. Although Jesus would be cheaper, probably
Its like when we brought Dembele, it was clear his first touch nor off ball movement was pretty poor in Dortmund. But the majority of us believed it could improve. It didn't. I also hoped Coutinho could play as a interior and improve his workrate off the ball and play faster. He didn't. Now I really want to believe Lautaro will improve his finishing but finishing is difficult to improve, its a natural trait. Look at Greenwood.
When we pay that kind of money, IMO we shouldn't hope/believe they can improve such big weakness, we should focus on players who play to their strengths. Doesn't really make sense for me to pay that kind of money and hope his finishing improve.
