Bottom of the Premiership with nine points from 24 games, the Black Cats have yet to win a home game this season following their Championship title of last term.
Robbie points out though that his former national team boss will not accept relegation as a foregone conclusion and will not be giving up on chasing wins with 14 games left to play.
"They showed that at our place and I've seen a few of their games," said the striker. "That's Mick for you, that is the character he is and he will never ever give up until someone tells him they can't get out of trouble.
"He'll have his team right up for the game, it is a home game for them with their fans behind them and he'll have them ready.
"That is the way he is, he doesn't like losing games. That is why he did so well with the Irish team - he doesn't even like losing in training.
"I am feeling for him at the moment with the situation he is in, but if anyone can turn it around, he can."
Sympathy for his old boss aside, Robbie insists there is only one outcome the team will be targeting when they arrive at the Stadium of Light for the 1.30pm kick-off.
"We are going there to get three points, we don't go anywhere to sit back and play for a draw," he added.
"If we want to push on to the next level, these are the games we must be getting something out of. I don't see any reason why we can't go up there and get the win."
Robbie Keane says the character of manager Mick McCarthy will see to it that Sunderland will fight to the finish.
