Chelsea boss Antonio Conte believes his side's remarkable turnaround in recent weeks has gone a long way in proving their doubters wrong.
The Blues finished 10th in the Premier League and after losing to Liverpool and Arsenal in back-to-back matches in September, another disappointing season was prediction.
However, a change of formation – to Conte's favoured 3-4-3 system – has seen the Londoners moved to the top of the Premier League table after winning their last seven matches.
After coming from behind to beat Tottenham 2-1 last week, Conte believes his side's doubters can no longer question their title credentials, as they prepare to take on Manchester City on Saturday.
"I remember in my first press conference that not many people trusted in Chelsea, in our work," Conte said.
"I think this must be a great strength for us to continue to work and to change people's opinions.
"We are working for ourselves, for our club, for our fans, to show that we love this shirt, we love this club.
"It's normal if you are a great team like Chelsea, and you play or are the manager of this great team, the expectation is always high.
"Sometimes it's right to be high. Sometimes you have to wait, because you are building something important.
"But now it's important to continue to work to show that Chelsea can fight for a place in the Champions League, can fight for the title, can fight the best teams in this league.
"We want to show we are working very well and we are growing. Saturday is another step to show us if something changed compared to the start of the season."
