Crystal Palace boss George Burley will field a mystery trialist - fresh from the World Cup - against Chelsea on Saturday.
The Eagles chief wants to keep the identity of the player secret until kick-off.
"I've got at least one international player who will play 45 minutes so we can have a look," said Burley. "He did play in the World Cup so he is at a good standard.
"I'll hopefully have another one on trial for Chelsea too - it is ideal to see these people in match action."
