After watching this video on Vucinic I'm now convinced that he could do a good job for us for the rest of the season and can see why Wenger is after him:

The pass at 4:45 is just class.
He can lead the line, play just off Giroud, or he can play in either the left or right wing slots. Wenger likes that kind of versitility and he seems to fit the bill along with having the technical attributes necessary to slot into the team easily.
Wenger wont go and get an out and out goalscorer because he's currently a believer in having multiple threats on the pitch and spreading the goals (and subsequently the risk) across the team.
Would be happy if we get him, whether its on loan or a permanent deal.
