GIOVANNI VAN BRONCKHORST admits Rangers were masters of their own downfall as they crashed to a 4-0 Old Firm defeat at Parkhead.
Celtic opened up a five point lead in the Premiership title race as Liel Abada netted twice and Jota and David Turnbull piled on the derby misery.
Rangers were lacklustre throughout a one-sided fixture and gifted Celtic their three first half strikes as the game was put to be bed by the break.
Keeper Jon McLaughlin was then solely culpable for the fourth with a wayward pass and Van Bronckhorst knows his side gave themselves too much to do on a wretched afternoon.
Van Bronckhorst said: "Of course very disappointed with the result and with the way we conceded the goals.
"I think it was a repeat of the game we played in February with quickly a taken throw-in and free-kick. We knew that was one of their strengths and both times we weren’t ready and we conceded goal.
"You know when you concede early goals like that you make them stronger and you make it more difficult for yourself.
"Of course disappointed with that, disappointed with the result. I think that is what I feel now.
"We prepared for these moments that they were able to be dangerous and we weren’t really. That is very disappointing because you want to play and give a good game.
"Of course you can always have goals against you, but not in this manner. That is not the way we need to concede goals.
"We had a very disappointing performance. As I said, we gave three goals away, which makes it hard when you come to Celtic in an away game.
"We have to take this one. Very disappointed we couldn’t give our fans the game we wanted.
"That is very disappointing. It is a loss for us, we have to take it on the chin and move forward after this."
