I just bought 19yo with 5* 34q (12p before 6*) cost around 4.53m (should be a fast trainer). The season is ending soon so what should I do between...
1. Use the green boost to train him to become 6* before the end of the season so he will be downgrade to only 5* at the beginning of the new season
2. Don't use any extra boost. Just let him develop naturally by playing matches but probably will not be 6* before the end of the season (he will become 4* at the beginning of the new season but should be 5* after playing few matches)
Which one is better and why ??
Thx in advance for your advice )
