Gus Poyet admitted Sunderland's 1-0 victory over Kidderminster Harriers was hard to analyse and was just relieved to reach the fifth round.
The Black Cats were strong favourites to knock out their non-league opponents and they got the job done thanks to Charis Mavrias' goal after just five minutes.
Poyet made wholesale changes to his side, with Oscar Ustari and Santiago Vergini making debuts and midfielder El-Hadji Ba handed a first start.
And, while the win was hardly emphatic, Poyet was just pleased to keep the momentum going.
"It was probably expected, but then we needed to win," the Uruguayan said on the club's official website.
"If you asked me what is important for us now, it's just to win games and to feel that we can be strong at home.
"Of course a new group of players playing together for the first time - I think they were very brave in the first 20 minutes - very, very good."
Poyet added: "It was very good [Mavrias' goal], he didn't think twice, it was a great strike and at that time it was what we needed.
"[There were] things that were missing; that last ball, that last cross, hitting the target with our shots.
"It was tough because that last ball is the one that you need to manage with quality, but I would say it's difficult to analyse this game.
"We need to just concentrate on Oscar Ustari, Santiago [Vergini] at the back and a few players that haven't been playing like Diakite or Roberge or Charis Mavrias - they got 90 minutes which is great for them.
"That was most important, and of course being in the draw tomorrow."
Opposite number Andy Thorn was delighted with the way his players approached their task, and admitted they were disappointed to be heading away from Wearside without a replay.
He said: "I was immensely proud of the players, I thought they were magnificent today.
"We set our stall out. We knew it would be really tough coming to a Premier League outfit and when we conceded as early as we did, sometimes you can end up with a cricket score.
"But I was really pleased with the way we regrouped and showed the character we did, the belief in what we are trying to do at the club.
"For us to be in our dressing room disappointed we are not coming away with a draw, it just speaks volumes for the performance the players put in."
