Joachim Andersen has told Crystal Palace they must fix a number of mistakes they made against Fulham when they face Bournemouth on Saturday.
Palace were beaten 3-0 at Selhurst Park on Boxing Day, their first competitive fixture since before the World Cup break in November.
Finishing the game with nine players due to Tyrick Mitchell and James Tomkins both seeing red, Anderson said the Eagles didn't execute some of the basics but they will analyse where things went wrong as they prepare for the Cherries on Saturday.
