I think Kulu's problem is that he's been over relied on to provide match winning moment, which he just hasn't done.
Him, Richy and Werner, strike me more as back-uo squad players, who CAN come in and make an impact, but probably can't be relied on to provide top quality consistency over 38 games...
That's a shame, cos in an ideal world, you'd have a squad of 22, 1st Team quality players.... But we don't, and, apart from one or two clubs, not many others do either to be fair.
We seem to have an AM/ forward line made up of 'back up' players, who would be fine to have around the squad,, if only we had better players ahead of them in the 1st team pecking order!
