The 25-year-old will leave Borussia Dortmund for Anfield on July 1 when his contract with the Bundesliga club expires.

The former Basel defender will vie with Alvaro Arbeloa and Steve Finnan for the right-back berth after he returns from Euro 2008.

Benitez believes Degen can provide an attacking edge down the right flank.

He told www.liverpoolfc.tv: "Philipp is still young but has gained great experience from playing in the Bundesliga with Borussia Dortmund and on the international stage with Switzerland.

"He also played in the Champions League during his time with Basel and so is used to top-level football.

"He is an offensive player with great energy and a winning mentality.
"His strength is going forward and I am confident he will be prove to be a quality addition to our squad.''

Degen admitted he took little time to agree to the transfer.

"When I received the offer from Liverpool, there was no doubt I would accept it,'' he said.

"They are one of the biggest clubs in the world and I am looking forward to the challenge of establishing myself there and playing in the best league there is.''
