The former Metz, Newcastle, Fulham and Manchester United striker - a title winner with United - joined us on tranfser deadline day from Everton.
Described by Harry Redknapp as 'bright and sharp, with great movement', Louis said he was excited by the prospect of joining a club with such attacking principles, fighting it out at the top end of the Premier League.
"It's a great feeling to be here, I'm really excited," said Louis.
"The squad is full of amazing players, always looking to win games and to play quick football. The speed of the play is fantastic. It's great to be part of that."
The former French international agreed that his style of play was a perfect fit for us.
"I thought about that straight away," he added.
"It is such an attacking side that always looks for the movement of the striker.
"I love to score goals and I see many opportunities with the wingers and the way we play. I just can't wait."
