Sunderland boss Martin O'Neill will take nothing for granted as he attempts to guide his side into the FA Cup fifth round at the second attempt.
The Black Cats head into Wednesday night's fourth-round replay at Middlesbrough having earned themselves a replay courtesy of returning hero Fraizer Campbell's equaliser at the end of last month.
Arsenal, who head for the Stadium of Light in the Barclays Premier League on Saturday, await the winners in a home tie the following weekend, although O'Neill will not even contemplate a quickfire return to Wearside for the Gunners until it is secured. He said: "We have a very, very difficult game that can go either way, and I wouldn't even look at Arsenal at all."
