Club supporters turned on the Newcastle boss this week after Sunderland’s first derby win at St James’s Park in 13 years.
Pardew said: "Some of the reaction has been a bit heavy handed, we think, I still maintain what I said after the game was correct. We have had a good week’ s rest and worked on things.
"The Europa League game definitely had an effect and a lot of clubs would have given right arm to be in the quarter-final of the Europa League and it was consequence of `going for it’.
"We have five games and time to do work with the team and time for them to be refreshed. They know they carry a responsibility of this club to get results.
"It was a great day for Sunderland and for us a tough day. I would rather play and give it a good go in the quarter finals of the Europa League and they can only dream of that. Next year there is always another game."
