(Reuters) - Chelsea have to put on a "high level" performance to beat a strong Arsenal side in Saturday's FA Cup final at Wembley, the Premier League champions' defender David Luiz has said.

In-form Chelsea are on course to win a domestic double and can select from a fully fit squad, while Arsenal are struggling with an ongoing injury crisis as four defenders are expected to miss the final.
