Russell Martin admits Swansea City let themselves down defensively as Gary Madine headed home an early winner for Blackpool in the meeting between the sides at Bloomfield Road.
The striker found himself unmarked at the back post to score what proved to be the decisive goal after just four minutes in the north west of England.
While Swansea enjoyed plenty of control against Neil Critchley's side, Martin knows the Swans need to be far more creative in the final third.
