I agree that we shouldn't "attack" players, but I believe we are all within our rights to point out their individual errors. And I'm sure Jose and the players concerned will be looking at them too.
For example, surely Lloris, Dier and Mourinho will sit down with the defensive coaches and have an open and frank discussion about what went through their minds for the first goal. Did they make a conscious decision to leave it for each other? Or was it instinctive? If it was the latter, how can the defensive coaches change that so the instinct becomes to put the ball into row Z if necessary, even if it means cleaning each other out, rather than leaving it and hoping your colleague will sort it out?
Similarly for the 3rd goal, Rodon will surely be asking himself why he didn't deal with that cross, as will Mourinho and the defensive coaches, so I don't see why we shouldn't.
There seems to be quite a lot of polarisation on this match thread with quite a few people in one of two camps:
Either:
1. We lost because of individual errors made by defenders (Lloris x 2, Dier, Rodon, Aurier), and there is little or nothing Mourinho could have done about that.
...Or...
2. We lost because the whole performance was terrible because the tactics, selection and subs were poor and that's all on Mourinho.
In reality surely there is significant validity in both, it doesn't have to be one or the other.
I don't like to see players as you say 'attacked' (some of the treatment on this forum of players like Winks and Sissoko is shocking, it's almost as though people wish them physical harm or misfortune...

There should be a great difference between 'hating' and 'not rating'...), but on the other hand it's absolutely legitimate to point at individual errors where they cost us heavily, as clearly they did in this game. Hopefully the in-house inquests will gradually improve some of the decision-making (though I'm not holding my breath...), as individual defensive errors are absolutely killing us this season more than ever. Whether those errors are down to poor players, poor concentration, or an overload of pressure on them brought about by Jose's tactics, is very much down to our individual interpretations, but there is no point in pretending that those individual errors aren't there and don't keep killing us.
