The Wales international has drawn criticism for recent performances.
He told Liverpoolfc.com: "In recent times I think it goes without saying it [my form] has been slightly disappointing, to be honest, but I am faithful and confident that I will turn things around on a personal level.
"It's games like Wednesday where, if I can be involved in some way, I can get my performance levels higher.
"There is no magic formula. I'll keep working hard and keep faithful there will be another performance like that just around the corner."
