I don't think he should be dropped, Ever? may be may not. But IMHO i wouldn't like to be the player who is being used for CL games and not week in week out.
Obv He will start ! he has the ability to play on the left jsut as good as he plays on the right !? just play naysmith on the right with him on the right, Kenny and Bettie up top
naw mate to be perfectly honest you dont have a clue ? if u think mucculoch is shite then u defonetley have something wrong with you so get it sorted .
