According to information revealed during the spot-fixing trial in London, an Indian bookmaker called Sanjay ordered Mohammad Asif and Mohammad Amir to let the Australians score more than 47 runs in the first 10 overs of the Lord's Test.
However, Amir dismissed Shane Watson and Australians were struggling at 1-23 at the end of the 10-overs.
Katich said conditions were difficult for batting in that match and he felt nothing dodgy.
"From my recollection it was business as usual in a Test, it was hard work and it didn't feel like we were getting any freebies. Those two were very good bowlers, particularly in those conditions.
"It never felt like anything dodgy was going on. They had us in trouble in that Test. They weren't far away from winning in the end," Katich was quoted as saying by 'Australian'.
Watson, who had taken five wickets in the first Pakistan innings of that match, said that he never suspected that anything fishy was on in that match.
"No, not at all actually. I didn't think anything untoward at all apart from trying our best and them trying their best to win the game," he said.
"We've played quite a bit of cricket against them throughout the last two or three years as well, with the Test series in Australia as well as over in England and some one-day series as well.
"I definitely didn't suspect anything of what's come out over the last year or so," he added.
