Gary Cahill is aware Chelsea took a big step toward the Premier League title by beating QPR on Sunday (12 April) but urges his side to complete their work in the "mouth-watering games" against Manchester United and Arsenal.
The Premier League leaders host Louis van Gaal's side on Saturday 18 April before a trip to second-place Arsenal the next week.
Having still one game in hand and being seven points above the Gunners in the Premier League table, the Blues just need 11 points from their remaining seven games to claim the title.
Cahill has praised how the team managed to secure the three points in a difficult derby at Loftus Road thanks to Cesc Fabregas's late goal as the team "know how potentially big the result could be".
"I was hoping one of the creative players would do something special and that was the case. It was a great piece of play down the wing, good timing of the run and Cesc slotted it away," the centre-back said to Chelsea official website.
"For us it was amazing, the atmosphere in the dressing room was fantastic because we know how potentially big the result could be."
And now Cahill hopes to finish the job on Saturday by stopping United's recent good form.
"They're mouth-watering games so everybody's looking forward to them. We've chalked another one off at QPR and we're getting closer and closer," the England international defender added.
"Next week we're playing against an in-form Man United team but we're playing at Stamford Bridge and it should be a good game."
After Manchester City suffered a new defeat at Old Trafford on Saturday 11 April, Arsenal and United are eventually the biggest threats in Chelsea's run to the double, following their League Cup victory.
