"We had a day off the day after the game and I went through things in my head then," he said.
"I just went home and I didn't want to speak to anyone, I just had to think about it myself. I realised you just have to move on and now I think I have.
"All you can do is focus on upcoming games, not ones that have gone before.
"For me the biggest thing was the timing of the goal, the last kick of the game and such an important game too. That was the most disappointing thing for me and everyone in the team.
"But mentally I am very strong anyway and I managed to get things quickly out of my mind. Coming back on Saturday was all that mattered to me and now it's Wednesday - just thinking about dong well if I get the chance there.
"Nobody wants to score an own goal but people make mistakes - and nobody will blame me if it's 0-0 on Wednesday and we don't go through.
"But nobody is even thinking about that, we are going to try and get a win and hopefully we will get it. Then the first leg result and the own goal won't matter. We know we can do it. It's a case of going there, having a go and knowing we can score. We are positive and know we can get a result.
"It's a big game and it's going to be a cracking night so hopefully we can come up winners in the end.
"We have to respect Chelsea for the team they are. They beat Manchester United on Saturday and haven't lost at home for God knows how many games so I think we have to respect that beforehand - but records are there to be broken. And we will go there and try to win because we have to and it's for a place in the final of the Champions League.
"So the whole team has a lot of confidence and we know we can have a go and score. It's going to be tough game but these games are why we play football."
