Mourinho called out Lingard earlier in the season because he knew he'd get a positive response. And that's what happened.
But then last week, Mourinho downplayed Rashford's mistake against Arsenal because he didn't feel a public rebuke would be beneficial.
Two completely different ways of handling two completely different characters.
Posters criticising Mourinho need to realise he's one of the best man-managers on the planet. Not just in football, but probably also in any industry you can think of. He knows exactly what he's doing.
Bringing up De Bruyne is missing the point. Mourinho's plan wasn't only to try and mould him as a player, but also to test his personality. Talent isn't the only factor when it comes to footballers. That's where Wenger has failed for over a decade despite having some of the best players in Europe. Personality is hugely important, and being able to stand up and be counted is something Mourinho demands from everybody. It's fair enough to question if that's always the best way to do things, but the fact his teams don't bottle it in May is proof enough to me that his methods work.
If Martial can't learn from this, he's not a Mourinho player. Mourinho's born a winner, so forgive me if I trust his judgement on this one. If Martial won't run through a brick wall for his manager, he's clearly got the wrong character. Hopefully he can develop that in the future.
