He said: "Being at Charlton is exactly what I expected.
"It's hard work, it's intense and physical and very demanding. But I wouldn't want to be here if it was easy.
"In fact the easy option would have been to stay at Reading and watch the games and play for the reserves but I want to play first-team football and Phil Parkinson has given me the chance.
"If Charlton get out of this predicament it will be akin to Reading winning the league. It will demand that much of us, but with the attitude we've shown we're giving ourselves a chance."
