New Sunderland boss Gus Poyet is confident he has the ability to work in the Premier League.
The 45-year-old Uruguayan, a former Chelsea and Tottenham midfielder, ended his first managerial job with Brighton in controversial circumstances back in May but is back with a two-year contract at the Stadium of Light.
On the subject of his time at Albion, he said: "My aim was to try and prove that I'm good enough for the Premier League and so here I am. I've got my chance now. It's going to be a difficult challenge, but I'm ready for it.
"When you're at the bottom in the situation that we are, everyone will say it's going to be difficult. The idea here is to believe and to be convinced. From what I see, I do believe that we can get safe.
"I need to convince the players and everybody. I need to make sure that players, staff, fans and directors believe in this opportunity that starts today. I'm going to play my part. I need to make sure everybody commits to the cause.
"You can see that they want to show everything the first day. Everybody wanted to train - even the ones that I wasn't expecting to. I just asked them to pay attention. The next two or three weeks, there's going to be plenty of information both ways.
"I need them to be really aware and to try to understand, to ask questions and to be involved. That will make it quicker. The longer it takes, the more difficult it is going to be. Most of the work now will be mental. It's about getting the right information.
"I've had one job as a manager so far and I was in it for four years. Every time a new manager arrives, he wants to stay as long as possible and prove he was the right choice.
"I am a confident, positive person but it's too easy to talk in advance. I want to prove it. I want to show you. When we get to the end of the season, I hope we are going to be sitting here smiling and I hope I can show I can do it at this level."
