The former Liverpool defender has heaped praise upon the Chelsea captain.
The defender has had a fantastic season as Chelsea have led the way during Jose Mourinho’s second season in charge, forming a formidable partnership with Gary Cahill at the heart of the defence.
In fact, the captain and his side have conceded the fewest goals of any side in the Premier League, with both Terry and Cahill both featuring in the PFA Team of the Year.
There was also a call for Terry to receive the individual award, and Carragher believes the defender is actually the best in history, never mind this season.
“I’ve always thought John Terry was the best centre-back I’ve seen in the Premier League era,” he said.
“I think that says it all because there’ve been some outstanding, world-class ones. People write you off and I think that did happen to Terry – he was getting a few injuries - but he’s come back fantastically.”
The former Liverpool man also says there is not much to choose between Terry and Eden Hazard for who has been the most influential player for Chelsea this year.
The Belgian has been in scintillating form all season, which led to him winning the PFA Player of the Year award, with his individual brilliance often leading the Blues to victory when the rest of the side have been found lacking.
Carragher though, says there is little to choose between Hazard and Terry.
“At what he [Terry] does, he’s the best,” he added.
“He’s been outstanding and I don’t think there’s much in it between him and Eden Hazard as to who’s been the most influential player for Chelsea. You’d probably just go with Hazard but Terry’s run him very close.”
