"We set our sights much higher than that and it's been a disappointing season. Hopefully, it gets better next year.
"From a personal point of view it started averagely and got better," he added. "I think 28 goals for Liverpool is the joint best I've done, but the main thing for me is I set this season to be a stepping stone really.
"To miss only two games with hamstring problems is probably better for me than any of the 28 goals."
