When we sign players, especially if they cost more than 10-20m, we shouldnt really sign them based on the notion that he might be good in 2-3 years, just because they are young. We should expect them to perform at a high level early on. Like Gabriel Jesus or Umtiti.
Thats true, but I think both Martial and Frenkie de Jong would do just that if you are referring to them. If we can't get Coutinho I would gladly welcome de Jong and/or Houssem Aouar. Martial is currently underperforming due to Mourinho IMO, still think he is doing good also at the national team.
Its sad we missed out on Gabriel Jesus, only 29m.
