You're just shitting on our players thinking other teams have it better.
Onana is a better ball-player and passer than any rival keeper bar Ederson, and even though he wouldn't get in over Vicario or Alisson at Spurs or Liverpool, he sure as hell would start for Chelsea, and probably Arsenal too. Obviously starts for Newcastle and West Ham too. Villa is debatable.
"Our defense is okay": Dalot and Mazraoui are both among the best full-backs in the league, just that both of them objectively cannot be considered the best. Both of them have a good case for being a top 5 right-back though. De Ligt and Maguire are both up there with the best organizer-type CCBs around, like Dias or Guehi. Yoro has best in the world potential. Martínez is probably the best passer (Stones and White being his only competition in this regard IMO), and most press-resistant CB/LB in the world. Shaw is the best traditional left-back in the world when he's fit. Malacia is a very solid inverted full-back rotational player. Which rival teams do you think have a better defense on paper other than Arsenal, City and Liverpool?
Fernandes is the second best #10 in the world after De Bruyne. But casuals will say "Odegaard is miles better" etc. I don't have the energy to argue against these types of posts anymore, with people who don't know what makes a #10 actually great, or just cannot judge talent and players at all.
Mainoo has a case for starting for every single team in the league, even City and Arsenal.
Rashford will be back to his best as well, which is 2nd best LW in the league after Son, as soon as he's not being played far away from the opposition goal as a touchline winger.
Hojlund is one of the few 30-goal per season potential U23 players in the whole world, whilst people are still debating whether he's better than Jackson or not.
The likes of Garnacho, Zirkzee, Amad and Mount would be key players at Villa or Newcastle.
This is why I'm ignoring large parts of posts I'm replying to. Whenever I write long posts and present many valid arguments, I get the same one-liner answer I basically replied to in the first place. What's the point then? These posters likely barely even watched the players they're so confidently talking about anyways. A new manager will likely come in at one point in the next 12 months and we'll see then who was right.
