Ended up buying 2 of the 4 ultimate packs available with coins as I was getting bored of waiting for my players to sell.
First pack - highest rated player was some 83 rated guy
Second pack - FS Guendouzi (sold for 575k)
I'm now contemplating whether to just buy the other two packs available for the hell of it. Anybody had any luck with these? Btw I'm not trying to brag but just curious as to what others have experienced.
