Carragher also had words of praise for Benteke after the striker - who Liverpool bought for £32.5m from Aston Villa last summer - came off the bench to win and then convert their controversial stoppage-time spot-kick following months of featuring as a substitute.
"I am pleased for him to get the winning goal," Carragher said. "A big-money signing and it has not quite worked out for him, but he is someone I look at and think he has had, not so much a raw deal, but you sort of fear for him at times.
"He has played [Divock] Origi at times and brought him on as a sub, it is like he has become the fourth-choice striker having come in as the number one with [Daniel] Sturridge maybe out injured.
"He has never gone to the press and complained every time he comes on and he just said in his interview then that you have to be ready when the manager asks for you."
And Carragher believes scoring the winner against Palace could give the Belgium international a much-needed boost in confidence as we approach the business end of the campaign.
"Now you could expect a different reaction from a big-money signing this summer if he does not play as much as he likes," Carragher said. "And I think he has conducted himself really well off the pitch - obviously he has to do a bit more on the pitch, but I think that will do him the world of good."
