Following Chelsea's 1-1 draw with Burnley on Sunday defender Gary Cahill said they can "see the light at the end of the tunnel".
The Blues weren't able to seal three points at Turf Moor but England international reckons they are edging closer to lifting the Premier League title.
"There's 13 games left so we'll chalk them off, hopefully with the right result," Cahill told ChelseaTV.
"We can see the light at the end of the tunnel in a way, but it's been a reminder [at Burnley] that it's not going to be easy to cross the line."
Chelsea missed the chance to move 12 points clear at the top of the league table as Robbie Brady's sublime free-kick in the 24th minute cancelled out Pedro's early opener in a tie Cahill said was much harder than they expected.

"It was freezing cold, snowing, the pitch was average, it was going to be one of those games," he said.
"It was a tough game when we had to roll our sleeves up and do the dirty stuff as well as trying to play football.
"We knew it was always going to be a tough game. Sometimes you have to dig in at places like this to get the point and maybe it is an important point, we'll have to wait and see.
"Every game's tough in different ways, so let's hope it's a vital point for us."
Chelsea (19) have scored the first goal of the game more times than any other Premier League team this season and have yet to lose (W16 D3).
Pedro scored his ninth goal of the campaign for Chelsea this season, surpassing his total of eight last term (2015-16).
