Wait a bit and see what your League is like, you might be the best Team and it wouldn't make sense to "tank." But having no budget left I would keep it in mind if the League looks tough.

Unless it is the best player ever, you should set a limit of how many Tokens you are willing to lose and stop at a that predetermined Round, I try to never go too far over Market Value unless it is a teenage gem, but he does looks nice.. I hope you get good performance for that price!!

Good luck this Season!
