Paul Heckingbottom is expecting Barnsley's Championship challenge to get increasingly difficult but is confident his squad is up to the task.
Barnsley have spent the two-week international break third in the Championship as well as being the top-scorers in the division with the best home record after three Oakwell wins.
But Heckingbottom told the Chronicle: "It's where you end up at the end of the season which is important. It doesn't mean anything to be third after five games. But the pleasing thing is that we have won three and scored a lot of goals and the players now know that they can have an impact on this league. If we keep up those standards, we have a great chance of getting a result against anyone.
"We have probably taken a few teams by surprise. But it will get more difficult to do that. I expect most clubs to keep getting stronger after their new signings gel together. Every game has been tough but it will keep getting tougher. We can't get carried away by winning a few games and we won't get too despondent if we lose a few either."
He added: "There's a good feeling at the club and around town. It's a feeling of 'wow, look what Barnsley are doing.' As long as the players give everything on the pitch you can't ask any more and, at the moment, we are getting the results as well.
"We have got to overachieve, we did it last year and we need to keep doing it. We are third so we need to try to be second after Saturday. If we're not then we need to move on to the next game and try to win that and get higher up again."
After a busy summer of incomings and outgoings, including the sale of Alfie Mawson to Swansea, Heckingbottom is focusing on getting the whole squad up to Championship standard.
"We're planning our season around the international breaks because we want to keep improving and getting faster, stronger and quicker. We are working the ones who aren't starting just as hard as the ones who are, while having the mindset of getting better all the time. We have had a little rest and we are now starting again with a new period of four or five weeks until the next international break.
"It's a case of getting everyone up to speed and knowing their roles. The boys who have been here a long time know exactly what we want from them. "We need to be able to change the team a little bit to freshen things up and keep the intensity without weakening the side. "It's different from last year because we have gone up a league."
