Neil Lennon has insisted that Celtic will be targeting victory over Benfica in their first Champions League group game.
Celtic face the Portuguese side on September 19 and Lennon believes that they will provide a serious threat, despite allowing Javi Garcia to join Manchester City last week.
The Glasgow club's manager said: "They sold two players in the window, Garcia went to Man City, and the other player went for a lot of money as well. They still have a very strong squad though.
"They may be weakened by those sales but they are still a formidable opponent. We are going to take one step at a time so our focus will be Benfica.
"We are at home and would really like to win that game and if we could get off to a good start it would really set the rest of the campaign up very nicely."
Barcelona and Spartak Moscow have also been drawn into Celtic's group for the competition.
