I stated without Mbappe, they no longer have the best attack.
Wherever Mbappe goes, that club will strengthen their attack. So if Real Madrid, they have hazard, mbappe, benzene, Bale, Vinicus, etc., which will be much stronger depth wise and the same as psg first 11 attack. Manchester city has grelish, mahrez, sterling, Jesus, de bryune, which like Madrid has better quality in depth than psg. Barcelona has dembele, greizman, depay, continho, Manchester United has Rashford, Sancho, Bruno, pogba, Greenwood, and so on. So these clubs can compete which such an attack without mbappe.
Losing Mbappe is like us loosing Bruno. Even though, we still have lots of quality in our attack, we definitely suffer a lot from his absent
