Aitor Karanka believes Middlesbrough have demonstrated their credentials ahead of a home match against Crystal Palace.
Middlesbrough will be full of confidence at home to winless Crystal Palace on Saturday but must avoid complacency, according to manager Aitor Karanka.
Boro have made an unbeaten start to life back in the Premier League, drawing with Stoke City and West Brom either side of a 2-1 victory away to local rivals Sunderland.
Palace will arrive at the Riverside Stadium with just one point to their name, earned thanks to Joe Ledley's injury-time equaliser in a 1-1 draw with Bournemouth prior to the international break.
