The Reds' Head Coach was pleased with his side's performance in Saturday's victory over Accrington Stanley.
A first goal at Oakwell from Dimitri Cavaré and an own goal were enough for Barnsley in their latest Sky Bet League One triumph.
The gaffer was impressed with his side who dealt with setbacks.
“We played well today," he told us. "It was a normal victory that you see from a side at the top of the league, we controlled most of the game. Even if it was not our best performance, we deserved to win.
“We know it is not easy to win against Accrington. I watched them play at Sunderland and they were very good. For 60 minutes they dominated. We were missing some important players too today.
"I told the players in this game to concentrate on us and not Sunderland on Tuesday. It is not so easy but the players showed focus.”
Victory on Saturday and results elsewhere meant it was a great weekend for the Reds, but Stendel remains focussed on the Reds only.
He said: “We cannot influence the results of the other teams but, on the other side, it is only good for us if Luton and Sunderland do not win. We will focus on winning our games until the end of the season.”
The opening goal was scored by right-back Dimitri Cavaré before Will Wood scored an own goal minutes later.
Stendel stated: “I was a little bit surprised that Dimi scored. It is a good pass from Cauley Woodrow and sometimes, when Dimi has these chances, he shoots with power but this time he used his head.
"It was an important goal of us. Then I was happy that we could get another goal before half-time.”
