Chelsea captain John Terry is adamant his team can displace Manchester United at the top of the Premier League with a victory at Old Trafford next weekend.
The Blues suffered from a drastic slump in form at the beginning of the year, but have turned their season around in recent times.
United losing to Arsenal on Sunday coupled with Carlo Ancelotti's men having beaten Tottenham Hotspur meant that the gap at the top was reduced to only three points.
Now the centre-half believes that potentially beating the Red Devils to eventually win the title will rank amongst the very best achievements of the club in recent years.
"It would certainly be up there, along with when we won it for the first time in 50 years," Terry said, according to The Guardian.
"There have been times when they were running away with it. United were 18 points clear at one point [sic - 15 on March 1] which I thought made them out of sight, so to get it down to three points shows what we've done. We certainly never give up and this is the ideal situation for us.
"United have still got some tough games to go. If we go there and lose, then fair play to them. But they know we're certainly capable of going there and getting a result."
The 30-year-old also hailed Ancelotti for guiding the side to resurrecting their title bid, despite previously having been on the fringes of the title race for a significant period of time.
"The manager's done the right job, kept the players hungry, and all the supporters have been like that as well – they've never let us give up and think it was over," said Terry.
"There's no bigger spur than going to Old Trafford and winning to put ourselves right in the frame for bringing the Premier League trophy back to the Bridge. It's the feeling that will drive us on."
But the skipper insists that despite the gravity of the situation in the past that included intense speculation concerning the future of the Italian boss, he retained the belief that the Blues could win the Premier League.
"I always believed," he said. "Through the season you have good spells, some not so good spells and some bad patches as well. At the start of the season we had our best spell. There was no doubt we'd have a bad one, and it was about coming out of that as soon as we could.
"It took us a few weeks to do that but once we did we've shown a turn of form at the right time. That's five wins now since we lost to [Manchester] United [in the Champions League quarter-final first leg] and all we could do was keep winning and putting the pressure on.
Terry also believes there are positives for both teams ahead of the game on Sunday.
He said: "They've got players who have experience and have been there and done it.
"Maybe that could be their key. But we've got everybody fit and have kept winning, we're playing well and digging out results. I think it's very tight. Maybe advantage them because it's at Old Trafford.
"When they came here in the league we showed what we're all about as a side, going a goal down and coming back to win that game, which has proved to be vital now."
