Rafael Benitez has failed to win over disgruntled Chelsea fans because results simply haven't been good enough, according to former Blues striker Jimmy Floyd Hasselbaink.
Chelsea regained third spot in the Premier League by beating West Brom 1-0 on Saturday but they trail leaders Manchester United by 19 points and sit four points behind second-placed Manchester City, who have played one game less.
Earlier this week former Liverpool boss Benitez - who has the title 'interim manager' at Chelsea - confirmed that he has every intention of leaving Stamford Bridge in May and criticised fans who continue to boo him.
But Hasselbaink, who scored 87 goals in 177 appearances for Chelsea between 2000-2004, told Goals on Sunday: "He was always going to find it difficult at the start. The only thing that could help him was going to be results and if you look at the results since he's been there, they haven't been that good and I think that's the problem. That's what you have to focus on.
"He can say 'they never took to me' but he knew that was going to be an issue when he signed. If he wants to get them on his side he has to get results and at least be close to Manchester United and Manchester City. But they have dropped too many points.
"The biggest factor in that, for me, is because John Terry hasn't been around. Normally he keeps everything together at the back - you win more games with him in the side than you lose. He was injured for a while so it was not a lucky period for Benitez.
"But even when he has been fit the results have not been there and the playing style has not been the best. That's my criticism. Fans are going to be fans and they make the club, so you don't really attack them - you win them over by results."
Former striker Hasselbaink hopes that he can now carve out a career in football management doing just that.
"I just want to manage a club that has the same ambitions that I have and that means playing for promotions and playing to achieve things.
"Some clubs just want to stay in their division and be stable. That's understandable for some clubs but I have always been a winner, so you want to at least try to play at the highest level and go for the highest level and compete.
"I was at Nottingham Forest for 18 months. I worked with Steven McClaren, Steve Cotterill, Sean O'Driscoll.
"I wanted to stay in football and when you go to 'the other side' and you work as a coach in the Championship, you can't keep the same status as you had as a footballer.
"You have to get back to basics and be humble and listen and, obviously, speak your own mind as well. But you have to be humble, especially when you are working for somebody.
"Yes, you can bring your experiences as a footballer to the table but it is longer hours and harder work."
