It's a shame he's a Raiola client, but he would definitely be a big upgrade at RB, if EtH or anyone could get Maguire to rediscover his form as a competent ball playing Central defender we should be okay.
@AjaxCunian that's completely different, City use that set up as they can use sneaky fouls to stop the counter attacks, whereas any throw in close to our box or a corner would be disastrous with tiny Central defenders.
I do hope we can get to a stage where we can dominate the ball most of the time, but that will take time, and during that time if we buy tiny CB's then we're going to get roasted.
