The now Reading manager took the sensational step to respond to a tweet with Bent’s quotes on his time at Derby by having a pop back.
A reporter from the Sun tweeted: “Savage from Darren Bent on Paul Clement: ‘It was inevitable he was going to crumble (at Derby). Training had changed and his philosophy from pre-season had gone out the window because we weren’t getting the right results. And ultimately he didn’t really like confrontation.’”
And Clement then responded saying: “I sense some bitterness here, which is normal if a player does not play much.
“It is never a difficult decision to leave out a player who is over weight and lazy.”
Bent, who was released in the summer and remains without a club, was infamously dropped by Clement for a match against Brentford a week on from scoring an 89th winner against MK Dons.
Bent had arrived late due to traffic on the way to the stadium and Clement said he couldn’t wait around before naming his team.
He said: ”Darren arrived late for the naming of the team which was unfortunate for him because it can happen to anybody.
“He got caught in a lot of traffic and I couldn’t be totally sure what time he would arrive. He did arrive in plenty of time to play the game but I needed to name the team and the bench so at that point I needed to make a decision and I made the decision to leave him out.
“It was not a decision I wanted to make but we have to get on with our preparation and we can’t wait.”
But Bent had praised Clement initially after he took over at Derby, admitting he was learning from the former Real Madrid and Bayern Munich assistant.
“He’s been really good, to be fair,” Bent told Sport magazine in July 2015.
“He has new ideas, fresh ideas, and he’s come from winning Champions Leagues and league titles – big, big trophies.
“He’s coached in some big, big games, and that experience is going to help us. We’re all taking bits of his advice on board.”
Clement’s Reading side lost to Derby last night in the Championship opener despite taking the lead after 52 minutes.
Tom Lawrence headed the winner in the 94th minute after teenager Mason Mount scored on the hour with a low drive to cancel out Jon Dadi Bodvarsson’s powerful header that had put the hosts in front after 53 minutes at the Madejski Stadium.
The result handed Frank Lampard a victory on his managerial debut.
“It was an interesting start. It’s great for us and that’s what I’m back in the game for,” Lampard said.
“It’s not going to happen every week, I’m fully aware of that. But those feelings are incredible.
“It’s hard to compare (winning as a player and manager) but that’s right up there with what I’ve done in my career – in terms of the moment.
“I don’t want to get carried away because I know it can’t be like this every week. But that moment was fantastic. “
