Black Friday has been a huge event in recent years for FIFA and with EA's content team being in full force this year so far I can't see it going missed, especially with the huge TOTW we have seen somewhat forced upon us. IF's have to be the focus with so really cheap options taking my eye.
The above are the investments I find to be value. They all are primarily for BF SBC's however I do think an MLS POTY is around the corner and from that we could see a very usable player from which I hope an MLS IF will be needed. Orban is currently the cheapest 82 rated IF which is good on its own but with Bundesliga POTM we could see huge rises on him and the same applies for Rondon and the Prem.
Disclaimer: I take no responsibility for lost coins, this is my personal stance on the market
