I would like to see him against Gastelum to prove that he still belongs to the top of the middleweight division and on the other hand it is a great opportunity for gastelum to rise even higher after win against Bisping. But as You forgot to mention Rockhold said before Romero fight that after that fight he is going to light heavyweight so in that case i would like to see him against Manuwa or OSP for the start.
