Lee Clark says he was embarrassed to see his Blackpool lose 7-2 at Watford on Saturday.
The Championship's bottom club were leading by two goals at half-time, but succumbed to another desperate defeat.
"At ten to four it was looking fantastic. At ten to five it was embarrassing," Clark said. "We’re deeply embarrassed by that second-half. To concede seven goals in any game, never mind a half, is very disappointing and frustrating.
"You just can’t play like we did in the second-half, at any level. We’ll take all the flack that is going to come our way in the next few days, and rightly so."
