The Black Cats head for Swansea on Saturday still looking for their opening Premier League win of the campaign.
They do so with Poyet preparing for his first game at the helm in the wake of Paolo Di Canio's departure and sitting at the foot of the league table.
Last season's League Cup winners Swansea are currently attempting to cope with the twin demands of domestic and European competition, but the Uruguayan insists none of that will count when the first whistle sounds at the Liberty Stadium.
Poyet told the Sunderland Echo: "It's a big contrast. We have a few problems. We have changed a manager and we have got a new group of players.
"But at 3pm, it's 11 v 11, one referee, two linesmen. It's about what you do in those two hours.
"It doesn't matter what's happened before. Swansea are in a better balanced position, yes they are, it's true. But that doesn't mean that they are going to win.
"We will go there to win. We need to win football games. We cannot go to places looking to get just one point."
