Asier del Horno is delighted with his move to Athletic Bilbao.
"I am very excited about pulling on the shirt again and playing for this club. I hope I can play some part on Sunday," he said.
Del Horno, who arrives on loan from Valencia with a view to a permanent transfer, believes the Basque side are on the up again after a disappointing couple of years.
"The last two years have not been easy for the club, but the president has worked hard and a lot of new players have come in. We need to change the mentality and build confidence, but I am certain we can do well," he said.
