A few more thoughts…
The problem is bigger than Mo.
A change at this point would not achieve much, if anything.
A change in the summer – but who? Guardiola going to Man City, Ancelotti to Bayern (probably – there or Man U)
Diego Simeone wouldn’t be much of an improvement. Don’t go down the ex-player route.
Jose needs to change, yes – but isn’t that the whole point of a long term plan? He has just delivered the championship.
He will be a better manager on the other side of this. He’s earnt the right to a bad season – however catastrophic it may end up being (as long as it isn’t relegation)
The air needs to be cleared. Either sack him or put out a statement saying that Jose will be manager next season whatever happens this. That will soon sort out which are the players and which are the passengers in the squad.
Personally I’d drop Costa and Hazard from the match squad completely (Mo is being too loyal!) – bring in Remy, Reuben, Bamford back from loan, get some young and hungry people in.
It might seem more expensive, but overhauling the playing squad – play the younglings! – is the way to go.
