Kamara endured a tough afternoon at Ibrox after being brought back into the starting lineup having started in the midweek win over Legia Warsaw on the bench.
Celtic dominated throughout and took the lead shortly after the half-hour mark. It was no surprise that Gerrard decided to make at least one change at the break, with Sheyi Ojo coming on to replace Kamara.
It has been a disappointing start to the season for the 23-year-old who was outstanding in the months following his January move to Rangers. But he insisted that Gerrard told him that the decision was made to try and give the Gers more of a presence in the final third.
"The substitution was a tactical change - that's what the manager told me. He wanted to go more attacking because we were 1-0 down," he said, as reported by the Record. "I haven't played as much this season because we have a big squad and the manager has rotated.
"But if I'm honest, I probably haven't been in my best form and I've not been as good as I thought I was last season and that's probably the reason I haven't played as much."
While Kamara has not been at his best so far this term, it was understandable that Gerrard seemed to think that an Old Firm game could bring the best out of him once again.
Kamara was sensational when the two teams previously met at Ibrox, with a moment of brilliance from the Finland international leading to Rangers' second goal.
And it would also be unfair to not note that he was not the only player to underperform at the weekend. Celtic seemed to win every battle all over the park, so Kamara is not the only one with plenty to prove once the domestic season resumes after the international break.
