IMO, Denis is one of those forwards a top class team have on the bench and turn to when plan A hasn't worked. He can come on and change the way the line is lead and ask the opposition a different question. I think that's what we'll see when Jelavic gets going...hopefully.
That's a fair assessment. Only worry is that will anyone else lead the work rate by example when he's off the pitch. Most of the season we've been like City last night. But I guess that's up to Moyes, too, and what I understand is that Jelavic has a decent work rate himself.
