You are dodging the question - I haven't claimed that all the creativity should come from one side, but rather than currently, the majority of our threatening play is done down the left, with Young and Fellaini both typically involved, and yet these are the two that you and others seem to feel aren't pulling their weight.
At present, for all their aesthetically pleasing linkups, I struggle to think of chances and dangerous moves that they have created - they merely recycle possession around the box and play it backwards or sideways. Sometimes the ball gets to Valencia who swings in a cross from the right, but that is about it.
Regardless of what you want from a midfielder, Fellaini is clearly not in the team to be a playmaker. He is generally neat and tidy in possession, he wins the ball back regularly, can hold the ball up, dominates in the air and is a goal threat, as well as being an asset when attacking and defending set pieces. This is quite plainly his game, and judging by the fact that LVG has continued to pick him in the starting XI, it would seem that the manager values those qualities in that position, otherwise we might have seen Di Maria or Mata in that role.
What an idiot
