Louis Saha: "I am very happy to be here at this big club.
"I have found a great group and working with them will be a real pleasure for me. I want to give my best. I am here to help the team during this injury (to Miroslav Klose) and I'm happy to do it. I know on Saturday it will be a big game against Napoli and I am here to help.
"In life you must always try to give your best. I am a very competitive person, so the important thing is to always do better. This is a great team and a great country. I am happy to be here."
Saha will wear the No. 28 shirt.
