Mourinho admitted his team were "lucky" to go in at half-time at 1-1 after Anthony Martial had cancelled out Callum Wilson's opener after what he described as some "absolutely awful" defending in the first half. Mourinho's side are now seventh in the table, four points behind fourth-placed Tottenham and nine points behind leaders Manchester City.
