He said, "I am not concerned at all. We lost two points but that happens."
"You can't win every game. We just have to bounce back next week and we'll be trying to do that."
Celtic's heroics in the Nou Camp made the team look tired yesterday, as we threw away yet another lead, to draw the game 2-2.
Pearson suggested Wednesday's game had a factor in our poor show yesterday, "We had a big game on Wednesday and that took a lot out of the players."
"We managed to come here and not lose the game. It is a setback but we haven't lost the game so we have to bounce back next time.
"We had quite a few chances to win the game but these things happen. We just have to get on with it and take the chances we create next time."
Hopefully now, we will see more of the young Scot, and he will get the run in the team he deserves - we know what he can do.
