Chelsea captain John Terry is confident Avram Grant's in-form side can go on a long winning run and maintain their challenge for a third Premier League title in four years.
Terry played his first match since early October in Saturday's 2-0 victory at rock-bottom Derby County, a result that extended the Blues' unbeaten run in all competitions to 12 matches.
Terry is keen to keep the sequence going, saying: "We need to go on a nice run now, 10, 15 games to push us up there.
"That's what we're aiming for and it was a good start at Derby. If we keep on doing that then we have a good chance.
"We need to maintain this form over the course of the Christmas period, the games come thick and fast.
"As long as we're at our game and keep everybody fit we have a chance."
