Middlesbrough boss Aitor Karanka claims Crystal Palace have no secrets going into Saturday's relegation scrap at Selhurst Park.
Both sides are fighting for their Premier League lives, with Palace in freefall in 19th place and Boro just three points better off after a winless start to 2017.
Karanka's side have an enviable record against other teams in the bottom six, taking 11 of 18 available points and losing just once, at home to Palace in September.
Winger Wilfried Zaha and centre forward Christian Benteke were on target for the Eagles that day and remain two of the most obvious threats in a team that builds around its wide men and their service for Benteke.
