Neil Warnock's side suffered a 1-0 defeat at the hands of Kenny Dalglish's team at Anfield on Saturday, courtesy of a Suarez header.
"I think he is unplayable," Orr told Liverpool's official website. "He's so strong, I didn't realise how strong he was for a small player. I love him. I'm a big Liverpool fan and to be on the same pitch as him was a pleasure."
"It's mixed emotions for me. I'm disappointed with the result, but on personal level, it's a dream come true [to have played here]. I've dreamed about this day for years.
"I think it's the number one fixture the lads look forward to. It's disappointing to come away with nothing, but I don't think many sides will come away from Anfield with anything this season."
