The Reds lost for the fourth time in their last five outings, a result that Samba knows they have to put right quickly.
Speaking after the match at the Madejski Stadium, he said: "It was a difficult afternoon, we lost again and it was difficult with only 10 men. Now we just need to look forward, to keep working harder because it is a difficult time. We need to wake up as soon as possible.
"We are professional players and we know that in football, anything can happen. If you keep working, if you keep believing, then I am sure that we have enough quality in this squad to get some points. That is why everyone needs to do that, to work harder and think about the next game.
"Nobody could have seen us in the position at the start of the season, but we are in this position, it is the reality, and now we have to be more focused on never giving up and looking forward. It is important for us, for the fans and for the club that we do everything to get the victory as soon as possible.
"It is not easy, but for every team it is the same situation. This is the league, it is the Championship and for sure, it ismore difficult for us as we are in this situation.
"We keep losing but we have to work, that is all I can say and we need to keep working."
