Barcelona's biggest problem right now is the toxic environment. Everything is criticized because there are many interests, whether political, fighting for the presidency of the club, the press wanting to put various people in the club as a coach. And Koeman in the middle of it all, of course he is the person of all this hysteria with more ethics and morals by far.
He left the Dutch national team a year before the European Championship to coach a club in the midst of an institutional crisis.
He was the first to set an example and lower his salary... and convince the players.
He was brave and put a lot of young player who right now is important for the club: Pedri, Araujo, Mingueza and this year Demir, Gavi, Baldé, any other coach who could be fired would have played with the veterans.
He also installed the ethic of hard work that he had lost with Valverde, you just have to watch and compare some matches and others.
And my opinion is that last year Barcelona did much better football than the previous 3 years with Valverde and even the last with Luis Enrique, in fact Barcelona was the second highest scoring team in Europe only behind Bayern Munich and that with all the problems.
Koeman has 2 wins and 2 draws with half an injured team, I can't imagine what would have happened if he had started like Juventus...
This is Barcelona and all its hysteria at its best
If Koeman is not fired, it is because there is no substitute and the president does not want to pay the compensation, just that.
