Obviously none of us know for sure, but going by how Poch has always operated Id suggest he has already done his talking behind closed doors and not got the desired response. Hence going public.
Im not a big fan of that sort of thing, but I get it.
Poch takes a huge amount of flack for the players in public, all the criticism etc falls on him and he protects them.
If he feels they havent supported him in the way he wants by playing the way he wants - perhaps its right he moves some of that on to them.
If that has been Poch's motivation, I can both understand it and forgive him for it. But it doesn't seem to be working. And to be honest I'm not surprised. We're third again despite making no signings, selling Dembele, having lots of injuries, and unexpectedly having to play in Wembley again for most of the season. If I was part of a group who'd achieved that, I think I'd be irritated (or at least demotivated) that as soon as we lost the Burnley game our manager was publicly questioning our mentality for not achieving
more - and in doing so buying into and reinforcing critical narratives from other fans, pundits and journalists.
Whether behind closed doors or in public, it seems to me the right and fair approach would have been to congratulate the players for achieving what they have in difficult circumstances, and motivating them to get top 4 this season before a title push next season - in our new stadium and with a couple of new players. Instead, after already experiencing a few seasons of falling short, I can imagine that continuing to demand even more (without being able to provide the conditions to support and enable more) could start to become wearisome and rather than energising.
This all makes me think of the CEO at the last company I worked for, a startup - he was brilliant at generating a sense of commitment and motivating us to punch above our weight, and we made loads of positive progress initially. But when we hit a tricky patch, his ambition and belief in overcoming all obstacles became a burden rather than a boon - because it morphed into refusing to acknowledge obstacles, and unfairly blaming us as individuals for failing to achieve more.
(Obviously I'm not suggesting by any means that Poch is this extreme, and I totally recognise that as things stand we are only talking about a run of 4 disappointing results. Just found it interesting to reflect on my own experiences of this kind of thing, in a way that might be relevant - we are all human beings after all).
