Both have a licence to roam - they cover ground, lose their opponents, are used as hit up players, and crumb as well.
They thrive on confidence, and have been given time to develop this. They are also given good ground time as forwards like this need.
Who is ours? Pettifer was hit up man for a while. Morton does it a bit. But we dont have a permanent roamer, goalsneak, 2 goal a game crumbing man.
I think this is Tambling. With time in this role, and with confidence, he will hit up (is good over head), his crumbing is ok and will improve. This will give him some direction, and time to develop his defensive side off half back.
I would back him for 50 goals a year if allowed to develop properly. At the moment he still doesnt know where he fits - and plays accordingly.
