Sunderland manager Gus Poyet has admitted that it is "difficult to analyse" his side's 1-0 win against Kidderminster Harriers.
The Black Cats booked their place in the next round of the FA Cup after they edged out the non-league side thanks to a fifth-minute goal from Charis Mavrias.
The club's official website quotes Poyet as saying: "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 Valentin 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."
The result marked the end of a successful week of cup action for Poyet's side following their League Cup semi-final win against Manchester United on Wednesday.
