He said, "It's a great, great honour. I want to do as well as I can for this fantastic club and that's what I feel today. I feel excitement and I'll try to do a good job."
On what he's said to the players, Ljungberg continued: "No, I think what I say in the dressing room always stays there. But in general terms, I think we have some great players and of course we've had some problems. We haven't had some results and that's what we've got to try to address. But how we address that, I'll probably keep to myself."
The Swede insists fans will see him on the touchline.
"Yes, of course. I think I get involved in the game. That's who I am. But at the same time, I try to step back and analyse the games. So it depends a little bit, so it can be a calm man or it can be a not-so-calm man. It depends!"
Asked about a No2, he admitted: "That's something I will work on a little bit and we'll let you know when we feel we're ready."
