The transfer is still subject to international clearance, and Knockaert has agreed a three-and-a-half-year contract with Albion until June 2019.
On the move, Albion boss Chris Hughton told www.seagulls.co.uk: ““Once I knew that there was a possibility that Anthony was available, he was somebody I was interested in bringing to the club for a number of reasons.
“He is a different type of player to the wide players we have here; he can play in three positions, on the left, off the front man, but predominantly in his previous time here in England he played on the right side.
“He is a very good technical, offensive player, and has experience of playing in the Championship, in a team who played a 4-4-2 system, and he is used to having a responsibility in the wide areas - but mostly it is what he can bring us offensively in terms of goals and assists.”
Subject to international clearance, Hughton has confirmed it’s likely he will be available for selection against Rotherham United in next Tuesday’s Championship fixture.
