Hughton
Brighton sacked manager Chris Hughton on Monday in what chairman Tony Bloom described as "one of the most difficult decisions" he had ever had to make.
Brighton, who were in the top 10 in December, have dropped to 16th in the standings.
Promoted Brighton are 11th in the league with 34 points and the FA Cup represents their best shot at silverware.
Signing a striker in the January transfer window will be one of the main priorities for Brighton and Hove Albion.
Brighton and Hove Albion coach Chris Hughton said that his team has to perform on a high level in Saturday’s Premier League game if they want to beat Manchester United.
Brighton was promoted to the Premier League this season, but they lost their first two games against Manchester City and Leicester City.
