Best to worst. Just the ones that Mourinho has played the most there so no Mitchell etc. I reckon it's Blind > Shaw > Young > Darmian > Rojo. There's clearly no 'right answer'. Two other United fans I asked at work both gave very different lists. Mourinho's preference seems to change every few weeks. He was adamant about Shaw being fourth best last season but he might see him as fifth now with Young getting starts in the position.
