Manchester City have been by far and away the top-performing club in the Premier League this season and Pep Guardiola’s men have only dropped two points so far this term.
The Citizens are currently eight points clear at the top of the Premier League table heading into their crunch clash against Manchester United at Old Trafford on Sunday.
Chelsea, meanwhile, are in third place as they look to try and keep themselves in the title race and challenging for the defence of their crown.
And former Chelsea star Lampard feels sure that only the Blues and the Red Devils are capable of catching the runaway leaders.
Speaking to talkSPORT, ex-England star Lampard said: “Manchester United are still there, and I think Chelsea will be the other main challengers.
“I think the others will struggle for the consistency to close the gap on a team who are playing so well in Manchester City.
“But we certainly can’t say it’s over at this stage, yet.
“What the other teams, other than City, need to do is try and stay in contention and hope for a blip with [sic] City.
“At the moment it’s not coming… but you have to stay in the game.”
Chelsea booked their place in the last 16 of the Champions League as group runners-up on Tuesday night after a 1-1 draw with Atletico Madrid at Stamford Bridge.
The Blues, who won the title in Antonio Conte’s first campaign in charge last term, now turn their attentions towards their crunch clash against West Ham at the London Stadium on Saturday lunchtime.
