Yes your players remain the same or better Q/*, but you end up missing promotion, prize money, taking part in the CL and all the fun. Also, you could never be sure to "win" everything or ending up with lower Q-opposition after a "season" under the ice.

What if you end up with T-buyers (no matter if were talking about the league, cup or cl) the season after all the training? Its a 50 vs 50 choice
