Terry, ruled out of the clash through injury, was forced to watch from the stands as Chelsea were dumped out of Europe with a 2-1 defeat at Stamford Bridge, losing their last-16 tie 4-2 on aggregate.
Without their skipper, the Blues’ back four were ruthlessly exposed by the runaway French champions, as 20-year-old starlet Adrien Rabiot and Zlatan Ibrahimovic scored to see PSG into the last eight.
And Clarke, who coached at the club under Jose Mourinho and Avram Grant, believes the display showed how much they would miss the skipper if he left, as rumoured, at the end of the season.
“I thought both of PSG’s goal last night were down to really poor defending, you can almost blame the whole back four,” he told the Alan Brazil Sports Breakfast.
“They missed John.
“They missed him for his leadership and his organisation skills at the back.”
Asked if he believes the Blues should keep their skipper, Clarke added: “Of course!
“I’m looking at that Chelsea team last night and thinking, if they get rid of John Terry they’ve got to buy two top class central defenders to replace him, and [after last night’s performance] they probably need to buy two full-backs as well.
“They’ve got a lot of work to do this summer, Chelsea.”
While many are urging the club to keep Terry, many others are urging them to offload another – Eden Hazard.
The Belgian has been a shadow of the player who was crowned last season’s player of the year. He’s yet to net a Premier League goal this term, with his two strikes for the Blues coming in the FA Cup.
He put in another disappointing display at the Bridge against PSG, was berated by fans for a half-time shirt swap and then requested his own substitution due to a niggle with 15 minutes left to play.
“Hazard has been a disaster this year to be honest,” Clarke said of the under-performing star.
“His form has been poor. Even last night, when you’re losing 2-1 at home, and I know it’s difficult when you need three goals to win, but you don’t come off with a niggle. You don’t ask to come off the pitch.
“I’m not a fan of the half-time shirt swap either, and I think those things irritate the supporters.
“If you’re not playing well and you’re doing these little things, you’re just going to get everybody’s back up.”
