Rafael has described Louis van Gaal has "one of the worst" coaches he's ever worked with, insisting that the ex-Manchester United boss didn't give him a chance at Old Trafford.
United turned to the Champions League winner who had previously coached Ajax, Barcelona and the Netherlands after sacking David Moyes towards the end of the 2013-14 campaign.
Moyes failed to pick up from where Sir Alex Ferguson left off at the end of his glorious 27-year reign at Old Trafford, and Van Gaal was seen as a safer pair of hands due to his impressive CV and extensive experience of coaching at the highest level.
