Newcastle United owner Mike Ashley was in attendance as they defeated Rochdale 4-1 to reach the FA Cup fourth round.
Ashley returned to St James' Park for the first time this season before talks with boss Steve Bruce about transfer targets during the January window.
Newcastle went ahead through Eoghan O'Connell's own goal.
Matty Longstaff, Miguel Almiron and Joelinton also found the net before Jordan Williams' consolation.
Newcastle, who have not gone beyond the fourth round since 2006, will host League One Oxford in the next round.
Rochdale had earned praise after coming from behind to force a third-round replay against the Magpies on 4 January after an equaliser by 40-year-old substitute Aaron Wilbraham.
