I knew it! 9* Bobo and quite deservedly so... He aint no Superstar now!!! He is a LEGEND!!!
You done it at the last viable opportunity to PT a player 9*, Although I must admit, I brought Miku back to 9* at age 26 the following season despite leaving the 22-25 training bracket. It's around 450 greens to go from 8* to 9* at age 26-29, your better off developing a "Bobo Jr" soon.
