Lazio chief Igli Tare has welcomed new coach Vladimir Petkovic.
"I realise the name Petkovic may be new to many and so there is a great deal of curiosity around him," said director of sport Tare.
"This was a courageous choice, but one based on facts. I have known him for two years and was impressed by his football, while he is also a great person.
"We have not made big changes in the rest of the staff, as we think Reja's collaborators produced great results.
"We are convinced that with Petkovic we will continue to grow just as we have done in recent years, as we want to improve both domestically and in Europe."
