Chelsea boss Guus Hiddink admits their defeat to Tottenham last month could have ended their title challenge.
Hiddink said: "We said before that we are still in the title race but now we regret even more that we lost points against Spurs. We have to keep fighting and keep the pressure on the teams above us.
"The pressure is also on us not to spoil more points, as we did against Spurs. We have to keep winning and with two home games now coming up we have to keep the pressure on and let's see what happens.
"We have a lot of very big games coming up and it's nice. It's April and May and it's the finish of the season and it's going to be very challenging for everyone."
