Jürgen Klopp expects Roberto Firmino to become a key man for Liverpool this season once he gets a run of games under his belt.

The Brazilian has appeared from the bench in both of the Reds' last two games - against Rubin Kazan and Southampton - as he steps up his return from a back injury.

His rehabilitation could continue with a start in the Capital One Cup against AFC Bournemouth on Wednesday, a prospect that will excite fans who are keen to get a further glimpse of the summer signing from Hoffenheim.

Ahead of that game, Klopp revealed that he has long been a big fan of the attacker, having monitored his development in the Bundesliga prior to his switch to England.

Commenting on the No.11's versatility, the manager said: "With the Brazil national team last time he played as a No.9, usually he's in attacking midfield, or second striker, or he can come from the wing.

"He's a pretty skilful player. There was a time around a year ago when he was for a few months the best player in the Bundesliga.

"From the first day on, everybody could see that he can be a very, very good player. 

"When I heard Liverpool took him I thought 'good choice'! 

"Of course he needs time but he's strong with the ball, he's physically strong, he's fast in a good football way with the ball, fast getting his body between opponent and ball.

"He's an important player for us, of course, and I hope he can play [against Bournemouth]."

With James Milner suspended for the cup clash with the Cherries and Jordan Henderson still absent through injury, Klopp has a decision to make over who takes the armband.

On the subject, he joked: "If I'm honest I didn't think about it until now, but I'm pretty sure will find one - a man with arms big enough!

"When I know who will play then the next thing immediately I think about is the captain of the team."
