Chelsea defender Marcos Alonso blames manager Maurizio Sarri's system for his problems with fans this season.

His performances have made him a target for criticism from Chelsea supporters, but he explains that Sarri's decision to change the nature of his role during the course of the campaign has been a factor in any downturn.

He told the London Evening Standard: "For me personally, the path changed. I started very well, then the manager wanted different things from me.

“After that I was trying to do what he wanted and then he told me he wanted to play like I was at the beginning of the season. So maybe that has conditioned a little bit the way of my game.

“I think I'm settled now. I am very happy at Chelsea and looking forward to finish the season with a win and a cup.

“Has the criticism from the fans affected me? No. Football is like this.

"The better team you play for, the more fans follow you and there are millions of coaches and managers around the world! Some of them understand football one way, some of them has another opinion.

“I am the best to judge when I play well and when I don't. Of course during the season you play some bad games, but it's been a good campaign.

“I'm always looking for more, looking to improve and get better. That's something inside me, I know I have to work for it.

“I don't really care about the critics or when people talk good (about me). It can't affect you. I'm the one to trust myself and to look for more. I had a good season and hopefully the next one will be even better."
