Ivanovic said: “We have changed a lot and have been working hard on a different way of playing. You always need time for it to start working.
“In the last two games, I know it has not been the usual Chelsea but if this way starts working, it will be very good for us and we will be very dangerous.
“We will get a run from that, so we must keep on that way. I know it's very difficult and is hurtful for all of us but the opinion of all of us in the dressing room was pointing in the same direction.
“We have to be positive and think altogether. Our minds have to remain on our way of playing. You know in your career that it can always go up and down and in the last week we have been down over the bad results.
“But I am sure we can get out of this stronger. We have to stick together and work harder. We have to believe in what we are doing and results will come."
