Udinese in their first game of the Serie A season.
The Juve coach was speaking at his pre match press conference and Allegri also spoke about his recent transfer activity.
“Udinese are a difficult team but we have to beat them,” Allegri told reporters at his press conference.
“We have to start the season well.
“To win the league we have to score 75-80 goals and concede 20-25, football is sometimes a numbers game.
“A lot of the top teams have strengthened like Roma, Inter and AC Milan.
“We can not forget about Fiorentina or Napoli either.
“We are not a complete team, we are still missing something.
“We have brought in a lot of players so it might take time for us to get to our best.
“[Carlos] Tevez wanted to return home, [Andrea] Pirlo made a personal decision and [Arturo] Vidal received a huge offer from a big club.
“We only sell players if they want to leave.”
