I don't know about Leben, if Lombard fights like he normally does then he'll probably gas trying to take Lebens head off. Wandy at this stage is a perfect match-up for him, plus he is a big 'name'.
It's a sad day when people continually put forward an ATG like Wanderlei as the ideal opponent for every limited slugger that needs a win. **** giving Lombard an 'easy' fight against a shot legend, if he's going to progress in the UFC he should be given the same tough assignments as every other 'star' coming into the organization gets. I'm not saying throw him in there with the most difficult fighter available, but let's not cherrypick someone made for him at their expense. If he insists on staying at mw, let's see how he copes with a live dog also coming off a loss, such as Leben or Munoz.
I don't think that Munoz would be able to take him down, and he has been shown to have a shaky chin. I think Lombard would flatten him.
