Allegri was asked his view on this week's arrivals.
"We needed to increase the technical level of the team and De Jong is a very good buy, especially in light of our game, as a midfielders that fits in.
"Our midfielders also score a lot of goals on average. We must continue along this path. To win games we will need our champions, as it was when Zlatan Ibrahimovic was here.
"Not all teams have champions of the highest level, only a few teams can afford them.
"Now we are pretty covered in all roles, there are still a few hours until the end of the window, but I do not think there will be any more news.
"With the players I have available I can now try out some different tactics."
