In the week prior to episode 90th, where Gohan was going to have a training fight against Goku in Super Saiyan Blue, a japanese magazine gave an advancement saying this was going to happen and that mystic Gohan was going to be able to hold his own against Super Saiyan Blue Goku. But in episode 90th what we've seen..
it's Gohan having an even match with Goku in base form. Later Gohan having an even match against Goku in SSJ2. Later a very brief fight between mystic Gohan vs Goku Super Saiyan Blue and finally Goku defeating Gohan using Super Saiyan Blue Kaioken.
Therefore, can it be said mystic Gohan can hold his own against Goku Super Saiyan Blue ? is he even or is he weaker?
