For those who underrate Kamara, i think it might be down to not really seeing or understanding the role he plays in the team - he is playing the role Jack used to play for us when he started here. There was a lot of people who similarly didn't see it with him, but of course since Gerrard has come in we've seen Jack transition from a typical number 6 to a fantastic number 8, and has become probably the most complete midfielder in Scotland this season as a result.
As for that number 6 role that Kamara has now occupied - Not flashy by any means but does all the quiet work - pressing, intercepting, passing forwards or to the wide men (creators), covering for full backs, recycling the ball and dictating tempo along with Davis (or Jack if he is playing deeper), creating space in the middle of the park and so on. Its absolutely key when playing European games or in International football where the standard is much higher and teams are all able to hurt one another.
Hope he doesn't leave because i really like him at Rangers but he's EXACTLY the type of player who would flourish in a league like the EPL. Also glad hes put his slow start to the season behind him and now getting back to his initial form.
