Marco Silva believes that a Carabao Cup win against Watford can kick start his side's season.
The Blues are struggling to build momentum, with each victory followed by a setback.
They won against West Ham United in the Premier League, only to lose at Brighton the past weekend.
Now they face Watford tonight, before they take on Tottenham at home on Sunday.
"We need the win to keep playing the Carabao Cup and of course, it's our ambition to go to the next round," Silva told reporters.
"But also after a good win, the mood and confidence will be different and it can support well our next (Premier League) game against Tottenham.
"But we have to think of each game at the right moment. Let's see how some players will be tomorrow... we have to be really strong to win the game.
"I want to see desire to play in the next round. It's clear our ambition and goal in this competition, it's not a moment to hide.
"We want to reach the final. It's a dream for our fans and we have to share that. We have since the beginning. We have to go step-by-step and the next one is the Watford match.
"It's good for us because it's at home, and the atmosphere will be what we expect. The passion of our fans in both competitions is really high. They will for sure be the 12th man at Goodison."
