The former Heineken Cup winning fly half firmly believes Warriors can kick on next season.
And the straight talking Australian insists he is coming to win games and to finally help the club deliver.
He said: "I'm very much looking forward to the move and it's an ambitious club. I think people see the facilities and what has happened this season and know they are not far away off being successful.
"It is something that interests me, being part of an ambitious club that is hungry for success. I know what players the club plans to attract and what it is building. I wouldn't come if I didn't totally believe in that.
"The Aviva Premiership is a very competitive league, but there is a real vision for the club and that is what attracted me.
"Richard Hill came over to Paris and I have had a few discussions with him about how he wants to play," he added.
"I'm coming to play No.10 so we need to share similar ideas and philosophy on the way the game is played.
"I am very happy with his ideas and I hope to add something of my own. I have expressed myself at various clubs and now I want to do that at Warriors."
Warwick has spent two seasons in the French capital surrounded by some fantastic players and admits he has relished experiencing a new culture and way of life.
But he revealed the lure of playing in the top-flight in England - having already shone in Ireland with Munster - was impossible to turn down.
"I've really enjoyed my time in Paris and playing in France is something I always wanted to do since I came to Europe," he said.
"My wife and I took the decision to go to Paris and experience the culture and city. Stade are a club with a massive European reputation and who play in a tough competition.
"The Top 14 is very similar to the Aviva Premiership in terms of competitiveness. It's a big difference to the Magners League where five or six teams dominate. Over here playing away is difficult against any club, in England it is the same, every game is hard.
"The Aviva Premiership obviously gets huge media attention and it's well documented how difficult it is to play in.
"Leicester Tigers and Saracens are through to the quarter-finals of the Heineken Cup so I know what a big challenge awaits me.
"But I am looking forward to being part of an ambitious team and having the character of players around me.
"I've had a few opportunities to play in the Premiership so I am now finally taking the step by committing to Warriors. It's the right time and it's the right way to round off my time in Europe."
Warwick admitted he had taken a close interest in Warriors since agreeing his move and was thrilled by the level of support at the club from fans.
"After my initial discussions with Warriors I took a keen interest in results and in the team's progress," he said. "The team has had narrow defeats to away to Sale Sharks and at home to Leicester Tigers, but if you can turn those into victories you are looking at the top six.
"I am going to a place where I feel I can flourish and add something to the team. I've met Cecil Duckworth and know a lot of money, time and sweat has been invested at Warriors. The club wants Heineken Cup rugby and let's not get away from it; that is what we have to deliver.
"The Heineken Cup is another level on the Amlin Challenge Cup, with no disrespect meant to that competition. Sixways gets big crowds for the Aviva Premiership and it would be fantastic to add a European flavour to that.
"I'm now looking forward to the rest of the season with Stade," he added. "We are in a similar position to Warriors where we are outside the top six and fighting to get up the table and make the play offs.
"We've got a few big games coming up and the quarter-finals of the Amlin Challenge Cup too. There is plenty to play for and I want to go out on a high before I become a Warrior next year."
