Pretty sure Denayer played on the left all the time for the EDS, with Facey on the right? Not sure positioning is exactly the strongest area to his game anyway, so I imagine he'd be fine on either side as he does a fair amount of running to get back into position anyway. Either way, I wouldn't see him being able to play on the left as a problem for Mangala, it would just be a bonus that allowed us to have only 3 CB's. You always need 3 centerbacks anyway, especially with Kompanys injuries, it would just mean that Denayer could cover either spot when neccesary, it wouldn't mean Mangala couldn't get a game (it would just be a lot like this year, but him playing the role of Demichelis)
Personally, I think if Denayer really hits the ground running, then Kompany is the one in danger, not Mangala. Mangala and Denayers games go together a lot better than Denayer and Kompanys imo. As good as Kompany is, he doesn't sweep up and cover for his teammate in the way that Demi and Mangala do, which Denayer would probably need with the way he likes to come out and challenge people, like Kompany. I think they'd be a bit too similar to play together. Either way, it would be a lovely problem to have!
