Only Frenkie, Messi, and Alba get into Leicester's current XI from the past 2 years IMO. Maybe Suarez but 2019/2020 Suarez was so poor compared to Vardy I can't be sure. I literally can't think of any other player that'd succeed there. They have a stronger right back, a stronger midfield in all key positions, a stronger defense, and a good (but not world class) left winger capable of scoring at least more than the wingers that were available at our club.
Really I thought it was ridiculous at first too, but the major reason why Leicester aren't rated amongst the elite clubs in Europe is because they don't have the depth and because they're not good enough to finish above the top 4 teams in the premier league.
Place that squad in any other league with the same coach and their recent performances, they'd be rated a lot higher as they'd be a regular UCL team. Yeah i know, ridiculous. But it is my hot take so I know most would disagree.
