You and many other say think that Gakpo is the best deal for Manchester United, but I disagree because of one reason and the reason is because Gakpo is a winger just like Anthony, Rashford, Sancho, Martial, Garnacho and Elanga. Manchester United has many of his kind, the difference is that he is younger and reigning for now. My opinion is that Manchester United should go for a full fleshed striker like Victor Osimen of Napoli and Manchester United
Last season, if I'm not mistaken, before Antony the priority was actually the name Gakpo there but indeed when the final moment Manchester United finally took Antony and didn't look back at Gakpo and now they want to target him again.
Gakpo is indeed more prioritized on the wing but indeed there are several other alternatives with him being a striker and trying out the 2 Striker formation for Manchester United.
However, the current price for Gakpo is clearly not cheap to buy.
