Norwich has signed defender Daniel Ayala from Liverpool on a four-year deal for an undisclosed fee.

The 20-year-old Spaniard becomes Paul Lambert's eighth summer addition as he looks to bolster a squad which secured successive promotions from npower League One to the Barclays Premier League.

Ayala joined Liverpool from Sevilla in 2007, but found his first-team opportunities limited at Anfield, and last season spent loan spells in the Championship at both Hull and Derby.

Lambert feels Ayala will add some much-needed depth for the challenges ahead.

Speaking last week to BBC Radio Norfolk, he said: "I just think you've got to have a lot of cover throughout the coming games and a long hard season.

"He's a young player and obviously played against us for Hull and Derby and I thought he was strong and aerial as well, he was somebody we thought could benefit the football club.''
