Gouffran pulled no punches in his assessment of Newcastle United's 4-0 home defeat.
"We are really disappointed, downbeat and feel very ashamed, especially for the fans," Gouffran told nufc.co.uk.
"We have got injuries and suspensions but we don't want to use that as an excuse.
"Everything went wrong. From the first minute we just couldn't get into the match and then we conceded pretty soon after. We paid for that and couldn't get going."
