Chelsea must not let the disappointment of exit from Europe risk derailing their push for the Premier League, says John Terry.
The Blues had no complaints, as their lack of ambition and failure to control a Paris Saint-Germain side reduced to 10 men for 90 minutes, saw them crash out of the Champions League on away goals .
“I think we'll regroup (on Thursday),” said the Chelsea captain.
“I'm sure the manager will sit down with the squad and go through stuff . After the game you get to ponder on it, and after that it has got to be forgotten, because the games come thick and fast and you can't keep down.
“Southampton will come here on the front foot (on Sunday), playing well, and if we're not at it, we'll drop points and slip away in the Premier League.”
Terry admitted that Chelsea failed to take the game to their opponents, and left it too late to come back when the chips were down.
“Instead of going for the jugular, you end up sitting there and waiting, and waiting,” he said. “And the longer the game goes on, it's playing into their hands.
“And they scored late-on in both normal and extra time . You get late goals, and you've got five or ten minutes to respond – it's difficult.”
Asked how Chelsea would respond, and ensure the domestic title challenge was kept on course, he said: “We've got four or five days until Sunday's game, and a couple of days warm-down and go-again training, then pick ourselves right back up.
“But as a group of players there's enough experience in the squad to rally round and get everyone going again.”
