Nottingham Forest manager Aitor Karanka said it is important to keep the early-season form going when The Reds travel to Wigan on Saturday.
Forest are unbeaten in the league and progressed in the Carabao Cup in midweek, and Karanka is keen to carry on picking up results when they visit the DW Stadium.
He said: "It was important to start in this way. We finished last season and we began to work right away as we knew we needed to change a few things. The summer has been really good and it was important to start working with the whole squad since the beginning.
"We are good but we have to keep calm. We are in August and have played just four games and I am sure that good things will arrive.
"It is vital to carry it on. Now, we have played well in three games; we didn't play well against Bury but with 11 new players on the pitch it was difficult for them.
"But we still went through to the next round and it is important to keep this run going, especially for the confidence. I would prefer to have the same problem next Saturday than to play badly and have to change three or four players for the following game. I prefer to have those problems every single game."
Wigan won promotion from League One last season and Karanka is expecting them to be up for the fight on Saturday afternoon.
"It will be difficult," he said. "Wigan are a recently promoted team and they had a good run. Last season, Sheffield United and Millwall had a really good season and Wigan are in that way. They have good players and it is a good club so it will be difficult, but once again it is about us.
"Sometimes you never know how it will go, because sometimes you can say that it is easier to play against the teams that have just been relegated but we played West Brom and the quality was there and we lost two points.
"I approach the game in the same way that we did against West Brom or Bury. We have to think about ourselves, to keep going with our style and our intensity.
"Wigan are a team that likes to play, they play good football and are aggressive. They were in League One last season so for them, this season, to compete in the Championship is nicer so it will be a tough game but it is about us."
