Funny. You said Coentrao can still improve because he's still young and not taking the same view on Bertrand and he's younger than Coentrao. The latter is better offensively but a suspect defensively and what you first want in a full back is the ability to defend properly, which Bertrand will give us that. And who's to say then, with Mourinho, Bertrand won't improve on his offensive play? As for Mourinho not having faith in someone as young as Shaw? Didn't he integrated Varane into the Madrid and eventually play him including trusting him in some of their big games as well? And also, Mourinho gave Davide Santon his full debut at Inter when he was only 18 and was played quite a lot till a serious injury hampered him. If Shaw is good and more importantly, a player that Mourinho likes, then he will definitely not be afraid to play him a lot in games.
