Newcastle midfielder Cheick Tiote has apologised to the club's fans after suffering the worst day of his career against Sunderland on Saturday.
The 3-0 derby defeat at St James' Park, the second in succession the Magpies have suffered at the hands of their arch-rivals, left the Ivory Coast international totally deflated.
The 27-year-old said: "All I can say to them [the fans] is sorry for this defeat again because we cannot accept that.
"It's two seasons now we have been beaten by Sunderland at home and this is the worst, worst thing in my career, so I just want to say sorry to them.
"That's football, we need to focus on the next game now."
Newcastle face the task of attempting to bounce back against Chelsea at Stamford Bridge next Saturday.
Tiote knows a trip to Chelsea may not represent the ideal opportunity to attempt to repair the damage of a poor, poor day, but he and his team-mates will travel hoping to do just that.
He said: "It's going to be hard, but we have got a chance. We have some good players in the squad, so if we do the right things, we have a chance to win.
"It's going to be tough because Chelsea are a good, good, good, good team. But if we do the right things, we have got a chance to win."
