Marco Silva says his "confidence in Everton's work... and the way we are playing" gives him belief the Blues can triumph at high-flying Chelsea on Sunday.
The Toffees head to Stamford Bridge having won four of their past five Premier League matches, including last weekend's impressive 3-1 success at home to Brighton & Hove Albion.
Silva's men have also caught the eye on the road so far in 2018-19, earning draws at Wolves and Bournemouth - despite playing both games with 10 men - beating Leicester City 2-1 and being unlucky to come away from Arsenal and Manchester United empty-handed after dominating large spells of those two contests.
The Blues boss accepts second-placed Chelsea, who are yet to lose in the Premier League this season, will be favourites this weekend but knows the progress his Everton team are making and insists their positive mindset gives them a chance of getting a reward in west London.
"I have confidence in our work, confidence in the way we are playing, seeing how our team is growing, playing better and getting better results," said Silva. "Of course it will be tough. I accept Chelsea will be favourites. It will be a big challenge for us but what I hope and what I expect is that we are ourselves on the pitch.
"They will create problems for us but I want to see our team be ourselves, play in our way. In some moments they will create, but when we have the ball we have to be ourselves.
"I can analyse the first five [away] games we played. The first two we played almost 90 minutes with 10 men, we didn’t lose and almost won both. We had a very good win against Leicester. When we played at the Emirates and Old Trafford, we performed well but did not achieve what we wanted. We were competitive in all of them, we compete to win in all of them, even against this type of team and I am sure we will improve this form. I don’t have doubts."
Silva revealed Richarlison is an injury doubt for the trip to Chelsea but confirmed the Brazil international took part in a training session on Friday and would be assessed again on Saturday before a decision is made over his availability.
With on-loan Kurt Zouma out of Sunday's match due to the defender being ineligible to play against his parent club, Yerry Mina, Mason Holgate and Phil Jagielka are in contention to replace the Frenchman at centre-back.
That is likely to be alongside Michael Keane, who was rewarded for his fine form this season with an England recall in midweek.
"Richarlison didn’t do the whole session today, he did some individual work," said Silva. "We will see tomorrow, we still have one session. Let's see how he will react after the individual work this morning. He is an important player for us, playing as a striker or playing as a winger
"If he not fit, it is a good opportunity for the other players to play in his position. This is football, when one problem happens you have to look to the solution. And the players waiting for their chance, they have all my confidence."
On Keane, the Blues boss added: "Since the first day of our job here I said the most important thing is to achieve good results. But to achieve that we have to develop our squad and our players.
"It is part of our job and when a player like Michael, after what was a difficult season [in 2017-18], is improving his performance…if he can go to the national team, I think that is part of our job.
Not just with him but we achieved this with the other players like Kurt Zouma and Lucas Digne. If they get into the national team I think it is really important for us and is part of my job."
