The Brazilian midfielder, who was a key component on the club’s 1-0 win against Barcelona in midweek, believes the players have found that extra boost in this crucial period
In the reverse fixture between the London rivals, the Gunners ran out 5-3 winners at Stamford Bridge in one of the most entertaining games of the year.
And the 25-year-old acknowledged that the Blues cannot suffer a similar fate this time round with their Champions League qualification hopes hanging in the balance.
“I wouldn't say we owe Arsenal, but our aim has to be to win the game,” Ramires told Chelsea’s website.
“It was bad to lose 5-3 at home and we need to win this one, not because of that but because we need three points in the Premier League.
“The defeat at home stuck in our throat, but we just need to win this game for our position. We have to do well in all competitions.
“We have gone through our bad phase and it motivates us to improve our position in the league now.
“The motivations for each competition are different, but it doesn't matter as long as we are motivated for every single game, they are all so important.”
Chelsea hold a slender first-leg lead over Barcelona in the semi-finals of the Champions League and sealed an FA Cup final appearance with a resounding win over Tottenham at Wembley.
And the Brazil international believes that his team-mates are improving their performances as the big games come thick and fast.
“Everybody is finding a bit more of themselves and giving a little bit more to succeed,” Ramires said of the Blues' recent upturn in form.
“The team has to be congratulated and I am sure we will get through this period.
“It's true, the last few weeks have been very intense but we have the desire, the right preparation, the right rest time, and this is what we need at this point in the season.
“We are letting through, and we will get through with our desire and determination.
'We are feeling very confident. Chelsea is a very big club and we have great players here that every other club in the world would like to have.
It is a privilege to look at our team, we have regained our confidence and now we have to just carry on with the momentum we have, picking up results.”
