Ian Royal I can't help but think Gunter's mediocrity is holding Obita back too.
I think that it's more to do with who plays infront of him. Jobi was a great mentor and support in that way, he gave Obita cover which allowed him to have freedom to be more attacking. Since then we've had HRK and John who don't provide that part of the game at all, it was a little better when Quinn was on the left but their understanding doesn't seem to be as strong as it was with Jobi. A little similar to how Gunter and McCleary are different players when together on the right and on form - their understanding is (was?) second to none within this team of where they would be, where they'd want the ball and the amount of support they would provide each other.
It's great having a team of talented individuals, but fundamentally you need those little linkages across the pitch to turn a squad into a team.
