vvd for dante, maybe an evo like varane or kounde evo to get them to 90 (if you can) grimaldo sbc if you want, or you can buy maatsen for under 50k, i would also save up fodder for any future cms or if you want to do a cdm like makelele i would advise that because it would provide some more defensive balance to the midfield.
you need to change silva, Kounde , Dante , or maybe Theo , but if you need Theo play with the 87 + card of Theo. If you have 500K under to change silva you can buy Valverde 90 , Sawa 91 , Sneijder 91. Okay instead of your centre back you can change them with VVD 89 , Lucio 89 , Rio 88
Hear me out buy Iago Aspas fantasy card as he is 91 rated and could become 92 and he is only 30k coins and he could probably replace Cantona or come in as a supersub.
