The ex-Aston Villa man says that he is in peak condition ahead of the visit of Alan Pardew's side, hoping for his side to bounce back after defeat against Manchester CitySunderland defender Carlos Cuellar believes that he is finally back to full fitness ahead of Sunday's visit of Newcastle and hopes that the Black Cats can bounce back from their 3-0 defeat against Manchester City.
The 31-year-old centre-back made his comeback from a hamstring strain against Roberto Mancini's side after two weeks on the sidelines and, following hard work on the training ground during the international break, he is raring to go ahead of the Tyne-Wear derby.
"This is a good opportunity for me, it's a derby game," Cuellar told the Sunderland Echo.
"The City game was the first one I played after my injury but now I've had a bit more time to prepare and I feel great.

"We have already showed how good we are defensively and how good we are attacking. We've had the opportunity to have a break, to relax and prepare for the game on Sunday."
Defeat against the Premier League champions saw Sunderland's unbeaten start brought to a halt but the Spanish defender is confident that Martin O'Neill's side can bounce back with a win at the Stadium of Light on Sunday.
"You have to learn from your mistakes but in Spain we say you cannot take your skin off just because you make a mistake or lose a game," he added.
"I think the confidence in the team is very high.
"When you lose everyone is unhappy, but if you look at the table and you look at the games we have played before that, you don't have to be scared or lose any confidence because I think the team is doing very well."
