KYLIAN MBAPPÉ - POTM Ligue 1 EA FC 24 Prices and Rating

Running an rtg and been saving up since the start of the game. Can complete all the 89s, 88s and 85s with all my coins and saved fodder. I still need 800k to complete the 87s and 86s. Is this A) possible in 23 days as an 11 win merchant and B) worth dumping everything including all my coins into the SBC?
