Karl Robinson believes Charlton will improve after their last-gasp 2-2 draw with Peterborough.

Injury-time goals from Ricky Holmes and Karlan Ahearne-Grant rescued a point for the Addicks.

Patrick Bauer went off with an injury, adding to Charlton’s long list of absentees.

Speaking about the result, Robinson said: “We’re frustrated obviously. The fans stayed and the team kept going.

“We’ve got Bauer, Harry Lennon, Jason Pearce, Tariqe Fosu, Ben Reeves, Lewis Page and Billy Clarke out.

“So I’ve got a lot of players to come back and Leon Best to get fitter. So Charlton are going to get better.

“We showed we’ve got a never-say-die attitude, Charlton showed they’ll put bodies on the line when the going gets tough.

“The passion from the fans - if that doesn't motivate you nothing else will. We do need it - the future of the football club needs it.

“We need to keep moving forward. We weren't at our fluent best. We were all over the place defensively. Out of position, we were defensively poor.

“I kept telling the players if we get one we’d get a second. Something had to drop to us at one stage. You've got to have that belief as a human being because without belief you’re nothing.

“In the 89th minute, we were 2-0 down and the fans were still singing. Walking off seeing the passion in their faces, there’s a unity here. The fans and players can achieve so much together.”

The draw sees Charlton remain in sixth, five points off the top two.
