You have gone from claiming that he is nowhere near PL standard to that question in the blink of an eye. Leading striker in a top 4 team and nowhere near PL standard are two pair of shoes. I think that he is the best striker in the Serie A right now, and I think that he has been a lot better than Sesko (whom I actually rate highly as a player) up until now.
Your claims are way out there. Rasmus was our top scorer in his first ever PL season and undeniably had an incredibly bad second half of last season. He has scored 14 goals for club and country this season. That is the most of any player owned by United so far. Bruno is second at 10 goals. Yes. It is not the PL league, but if that is your sole argument, there can be no discussion. That means if you are not playing in the PL, you are shit. Kane, Mbappe, Lewandowski etc. Their goals aren´t worth nothing because some of them are scored against Cadiz, Augsburg or Leganes. That is so weird.
Could Rasmus lead a top 4 team in the PL right now? Well we are not a top 4 team right now, are we? But yes. I think he could. He is clearly behind Erling Haaland, who is a monster. I would also see him behind Ekitike so far, but thats it. He has been on par or better than any striker at Villa (Rogers and Semenyo are wingers) or Arsenal so far this season. Has Watkins, Gyokeres & Co. really been better? I don´t think so. Should he be the sole option in a PL top 4 team. Never ever, but that goes for any striker and any club aiming for the PL top four. It was scandalous that we did not have a proper alternative to Rasmus in the two seasons he was here. That is unworthy for a club of our size. It also meant throwing an out of form young player under the bus for months exposing his weaknesses and robbing every little bit of confidence last season.
Would he function here now? Not like he does in Napoli. The Amorim system is still the Amorim system, where strikers are not fed but scraps. He is more clinical than Sesko though, so he would probably have got a few more than the slovenian, who is struggling at the moment. I want Amorim out ASAP.
