Chelsea midfielder Ramires has warned title rivals Manchester City that the Blues will not suffer a dip in form before the end of the season.
The Blues are currently top of the pile with 21 games gone, two points clear of Manuel Pellegrini's side after they dropped points against Everton last weekend.
Chelsea started the season on fire and were unbeaten in all competitions until they fell to Newcastle on December 6, but since that defeat they have gone straight back to winning ways and have only drawn one and lost one of their last nine games.
Ramires is back fully fit from a spell on the sidelines with a hip injury, and says Chelsea will maintain their high standards until the end of the end of the season when he hopes the Blues will lift their fourth Premier League title and their third under Jose Mourinho.
"The standard isn't going to drop because everyone in the squad has a lot of quality," he said. "It's very good for the coach and the squad to have that healthy competition among the players for positions."
The Brazilian added: "It's definitely a good problem to have, when the team has a lot of quality.
"A team that wants to win competitions and be champions can only gain from knowing that, if you change the players, you see others coming in who you know are not going to lose the momentum.
Chelsea looked to be strong contenders for the title last season, but a bad run of form which saw them win just two of their last six in all competitions meant they had to settle for third place in the end.
Along with the Premier League, Mourinho's men have a Capital One Cup semi-final date against Liverpool, while they remain in the hunt for the FA Cup and the Champions League.
Ramires believes Chelsea are better equipped to deal with the pressure of competing on four fronts this term thanks to summer arrivals like Diego Costa and Cesc Fabregas.
He explained: "Last season we were okay but this season we have improved a lot compared to the last few seasons - everyone can see that.
"We were behind on points trying to catch teams in the past and now we're at the top of the League, even if Man City are right there with us. At this moment we know we only depend on ourselves.
"We have to make sure we get the three points in our home games and then we go to our away games trying to get more points and fight for the title. We are in a good position."
