He has had more than 60 games with us, that is more than enough to judge what he can and can't do. Plus it is not like this is his first mangerial stint, basically every problem he is having with us is the same issues he had at other clubs especially at his last job with United.
You need to look at how he won those trophies, which lets be clear he has not come close to doing yet. We are in the League Cup final because of the draw not because of our good play. We are in the round of 16 in Europa because of the draw not because of our good play. If we win the Europa it will be because we continue to get the luck of the draw, if we face good teams we will lose. If we win the League Cup final it will be because of absolute luck not us outplaying City.
Luck and draws are not sustainable year to year. What happens next year when we don't get the same luck and draws and now have to rely on form which we have seen has been awful in a year and half under Jose, was awful with United and tends to decrease at every stop he goes to.
Well ok. Luck of the draw it may be when in the end it's winning that matters. No gives a shit about the luck of the draw that have won things. If we win a trophy..or two (Europa would next round will get difficult so to win that will that will take some doing) then he will not be sacked. Maybe he will get another season. City deserved to lose when we beat them could happen again and I don't think anyone cares if he comes of bales ass and goes in to win it
