Sometimes i dont understand CAF at all, one day they mocked players like McTomminay due to his technical's deficiency then the next day they want to add another technical's deficient player to this club? Can you imagine the Ronaldo-Nunez's partnership flourish? i dont. If this Nunez kid struggles technically in the Portugese League what chance do you think he can do it in PL where everything is faster and harder? Just Imagine this: How long do you think it will take for him from receiving to passing the ball before the oppo players closing him down? Hard Work should be a given requisite, not something you actively looking for from a player, like you buying a new car, the car should be able to move that's a given the other requirements came afterward. Benfica are notorious for selling players above their true values: Renato Sanches, Victor Lindelof, Joao Felix, and Ruben Diaz (yes i put that City's Diaz who looked so average in EURO without top DMs and FBs shielding him) so I would be extremely cautious before signing any more players from them.
Get a new striker who can work together with Ronaldo, you know the likes of Rooney and Benzema, players with superb technical ability while never shy away working their socks off.
