The forward admitted he was his own harshest critic and that he is not happy with his goal-scoring output so far. However, he still stressed that injuries have taken their toll on him.
"I expect to do much more of course, I always do that. Even when I do really well, I want more, so that's not a problem for me. But yeah, I'm trying to stay positive, trying to work to do better and that's what we're looking to do," he said. "Yeah, of course. I think obviously I'm the first one to know and I know best when I'm doing good and when I'm not doing good. So I don't need anyone to tell me how I'm doing, so that's not a problem for me."
When asked if he had felt at 100 per cent at any stage for Liverpool, Isak replied, "I would probably say no, physically. I probably haven't felt at my best. But yeah, that's not really the way I judge myself either. When I'm on the pitch, I want to do well anyway. But yeah, obviously, there's more of me."
