Liverpool goalkeeper Caoimhin Kelleher is available to make his first appearance of pre-season against German outfit Mainz.

Injury saw the Irishman miss Liverpool's first two preseason friendlies against matches against Wacker Innsbruck and VfB Stuttgart on Tuesday.

But the 22-year-old will be fit to play against Mainz on Friday.

Kelleher told Liverpoolfc.com: "I just had a slight little knock on my knee but it's nothing serious so I'm back in now and ready to go. Yeah, I am [fit to play against Mainz]."

With Alisson away at Copa America, Kelleher has been given a more senior role in the Reds squad, a role he is relishing.

"Yeah, I'm enjoying it," he added. "It's a new challenge for me, it's a bit more responsibility on myself and yeah, I'm enjoying it. I'm just taking it as it comes, really."
