Martin O'Neill has warned Sunderland fans not to expect too much from the Black Cats in the FA Cup.
Sunderland take on Middlesbrough tonight in a fourth-round replay after a 1-1 draw last month.
"If a Sunderland fan asked me if it was worth betting on us to win the Cup I would say keep your money in your pocket," O'Neill said.
"Honestly, that tenner may buy you something, not a lot of fresh air."
Sunderland are currently eighth in the Premier League with 33 points from 24 games.
