they were defending a one goal lead and Leicester threw everything forward including Schmeichel, so of course you use your last sub to waste some time. You also don't take off your tallest players like Fellaini or Ibrahimovic ... Mata was simply the shortest player on the pitch so he took him off, Mourinho explained that fine after the game. It's probably not smart to do it to Mata because everybody knows their history and those journalist idiots will obviously look to make a story out of it. Mata was brought on instead of Mkhitaryan when they needed a goal, I highly doubt Mourinho did that to humiliate him in the end.

May be wrong, but I'd read more into fact Mata brought on when Mourinho needed a goal rather than him being taken off when protecting it.
