Liverpool's new £17m full-back Glen Johnson will make his Liverpool debut in Switzerland today with boss Rafael Benitez insisting he is worth the money.

Johnson will play in Liverpool's first pre-season friendly against St Gallen.

Benitez admits, like Manchester United boss Alex Ferguson, that the transfer market has gone mad this summer.

“The market is crazy, but you must pay good money for good players.

“The money for Johnson is OK. He is English, an international with quality and he is worth the money.

“He is a very good attacking player. If you try to buy a winger it can be £50m to £60m at current prices, but Johnson as an offensive full-back can give us more options, especially when we are at home and teams are defending against us. Going forward he will give us something different, something special. He is a good addition for us.”

Benitez has 24 players at the club's Swiss training camp, and says: “Our idea is to use one team in the first half and change it at half-time.”
