Marouane Fellaini has gone from villain to hero at Manchester United, but the Belgian believes the level of criticism he attracted last term was unjust.
Fellaini was ineffective for David Moyes and became symbolic of the malaise at the club when he failed to deliver on his £27 million price tag last season.
But the 2014-15 campaign has been a different story and Fellaini is in good form having started every game in United's run of six consecutive victories.
The 27-year-old feels that his early difficulties at United made him a stronger player, but he insists he didn't deserve such harsh criticism.
"Last season we didn't play well as a team and it was easy for people outside the club to say it was me because the manager brought me with him, but that was something I had to deal with," Fellaini told The Times.
"It was a difficult moment because in all my career I hadn't experienced anything like it.
"I learnt a lot. I care about what people have to say, of course, but my concern was for my family, my mum and dad and my brothers, because when critics are saying bad things about me, it will have been very hard for them."
Fellaini then stressed that United must do better than last season and set the target of a top-four finish.
“Last season was not good enough for Manchester United,” he admitted.
“We know that and we are working hard to put that right. In some ways it is too early to talk about the title because we are still building and it is only December, but we are winning matches consistently again and when that happens your belief grows.
“At the very least we have to be in the top four - we must do that. I wanted this challenge.”
