I think Marko may need a loan spell at a club where he can be the "main man" in order to really develop further. For me, he has all the raw ingredients -- size, athleticism, power, technique, crisp passing, a powerful shot, and an eye for goal. The problem is that he isn't quite consistent enough to get ahead of our current crop, but he needs games to continue his development. I think he'd be a regular starter at a club like West Ham and he'd probably get a solid 10+ goals if he played regularly. A season like that and he'd be ready to compete for a regular place again next year.
