Said Lotito: "I appreciated Klose's moral qualities, as he is a very professional figure who will give this team a step up in quality.
"I have to thank Cissè, as he had other offers, but firmly wanted to join Lazio. He wishes to prove his worth in Serie A after recovering from two very serious injuries. He has great strength of character.
"With Cissè and Klose in attack, Lazio will go far."
