Robbie Simpson gave the visitors a shock lead at Anfield with a stunning strike, before goals from Craig Bellamy, Steven Gerrard, Jonjo Shelvey, Andy Carroll and Stewart Downing wrapped up a 5-1 victory for the Reds.
Dalglish told reporters: 'The scoreline was a bit flattering, really. Oldham did their club proud, did their manager proud. They created a couple of threatening situations for themselves, especially in the first half.
'Getting back as quickly as we did with the equaliser was a great help, but I think it was important for us to give the players who haven’t had much time [on the pitch] than the others, to give them a run out as well. Fabio [Aurelio] got his first 60 minutes of the season I think.
'For us there were a lot of positives coming out of today’s game; Stewart Downing scoring, big Andy [Carroll] getting a goal, Jonjo [Shelvey] scored, Steven [Gerrard] with a penalty. A few positives, but I don’t think the scoreline represents the distance between the two teams.'
The Scot also reiterated the need for his squad to gain full fitness and acknowledged the importance of games like this to help players on their way to achieving 100 per cent.
