John Terry has been rated as the Premier League's best-ever centre-back by Jamie Carragher.

The Chelsea captain has been at the heart of his club's defence for the better part of his near two-decade career and former Liverpool star Carragher suggests he is the most influential player in his position since England's first division changed over to the Premier League.

Carragher also felt that perhaps Terry should have been in the running for the PFA Player of the Year which was won by Eden Hazard on Sunday.

"Yes, Terry should be in the top six players," Carragher said on Sky Sports after Chelsea held Arsenal to 0-0 draw which has given them every chance of winning this season's Premier League title.

"There's no doubt that, just behind Hazard in this Chelsea team, Terry has been the most influential.

"We've seen (Cesc) Fabregas, (Nemanja) Matic and Diego Costa feature in the early part of the season, but if you look at Terry's display today he was outstanding.

"We talk about Chelsea being a defensive team, but sometimes you've got to say they defend brilliantly, and Terry is the best.

"There have been a lot of great centre-backs in Premier League history, but I think he has been the best that we've seen."

Carragher added: "For the next 20 or 30 years, that position at the near post, when we see other defenders doing it we'll call it the 'John Terry' position.

"You can't always find yourself in the right position to put your head on things and clear things, you've got to have an understanding of the game.

"We're not just talking about a big aggressive centre-back, Terry is always in the right position.

"His understanding of where to be, his reading of the game and reading crosses cannot be matched. I don't think we've ever seen anyone better."
