Derby County head coach Paul Warne admitted he was “embarrassed” by his team’s Carabao Cup exit at home to Blackpool.
Warne’s side were booed off at half-time after two goals from Jake Beesley gave Blackpool control they never relinquished.
Beesley pounced in the seventh minute when Derby’s defence failed to deal with a cross from the left and after Owen Dale missed a great chance for a second, a defensive howler gifted Blackpool another.
Callum Elder’s 32nd-minute back header beat goalkeeper Josh Vickers, leaving Beesley to fire into an empty net.
Derby improved after the break and although Conor Washington forced Richard O’Donnell into a save in the 55th minute, a comeback never looked likely.
Warne said: “They were better than us from one to 11, they embarrassed us at times in the first half, we were deplorable with our performance.
“I openly admit I was embarrassed, I’ve never managed a team that’s been booed off at half-time and rightly so. The second half was significantly better but way below what we expect.
“The first half was honestly painful to watch, it’s hard for me to say because they are my team but I can’t sugar-coat performances like that.”
Blackpool head coach Neil Critchley was delighted with his side’s performance at their Sky Bet League One rivals.
“I thought we were excellent first half in and out of possession and played some really good football,” he said.
“Second half I thought we defended very well, I’d just like to see us see the game out with a little bit more possession and keep the ball more than what we did, we turned the ball over too many times.
“But to score two goals and keep a clean sheet, it’s been a good start for us. We had good control, good spells of possession and we were always dangerous.”
