John Terry says it is now up to Chelsea's Premier League rivals to show they can stand the heat in the title race after he helped the Blues secure a 1-0 over Everton earlier today.
The game at Stamford Bridge looked like it would end in a 0-0 draw, only for Chelsea to strike late on.
Terry appeared to jab home Frank Lampard's free-kick in the last minute of the game, although replays suggest it may go down as an own goal.
The win means Chelsea are now four points clear at the top of the table ahead of this afternoon's 3pm kick-offs, in which both rivals Manchester City and Arsenal are involved.
The Chelsea skipper says the hard-fought win against the Toffees has laid down the gauntlet to those two teams, who now need to prove they can last the distance at the top of the table.
"Recently dropping points away to West Brom, it's important to pick up three points at home," he told BT Sport after the match.
"We're top of the league and sitting well. It's down to the others now to catch us."
Despite the confusion over who scored the winner for Chelsea, Terry - who is out of contract in the summer and will leave Stamford Bridge then as things stand - insists it was his goal.
"It was a great ball from Lamps. I just managed to get a touch on it and I think it came off (Everton goalkeeper Tim) Howard in the end as well but I'm delighted with the win and the three points,' Terry explained.
'They made it quite difficult but they're a very good side and playing well under (Roberto) Martinez and it was a tough game today.'
Chelsea will now turn their attention to Europe and their next game in the last 16 of the Champions League, against Galatasaray on Wednesday.
