Manzano is under pressure after a poor season so far.
Diego insists: "I am 26 years old and this is not the first time I'm in a situation like this, it is still not very complicated. But it is a time to improve. It is a situation in which we are all together and we all have responsibility.
"Not only the coach, but also the players. We have to change together and I am sure that we will change quickly."
