Berlin - Borussia Dortmund boss Thomas Tuchel admitted there
was 'room for improvement' after his team lost 1-0 to Athletic Bilbao in their
German Super Cup warm-up before facing Bayern Munich.
Bundesliga champions Bayern, under new head coach Carlo
Ancelotti, are Dortmund's next opponents at Signal Iduna Park on Sunday for the
German Super Cup in the traditional pre-season opener.
But Tuchel's experimental 4-1-4-1 formation failed to break
the Bilbao defence, despite fielding an attack boasting Pierre-Emerick
Aubameyang, Japan's Shinji Kagawa, plus new signings, Germany forwards Mario
Goetze and Andre Schuerrle.
"There is a lot of room for improvement, when we
analyse the game, we'd do well not to expect too much for Sunday,"
admitted Tuchel after Tuesday's defeat in St Gallen, Switzerland.
"We were very tired and didn't manage to put into
effect the things we have planned.
"I have the feeling that although we want to, we are
not in a position to put in a top performance after an intense training camp.
"There is no question we can do better."

Dortmund put out a statement after the Bilbao defeat to say
Germany winger Marco Reus is on course to return to training in mid-August from
the groin injury which ruled him out of Euro 2016.
Tuchel had said that timeframe was "impossible"
and that he would be "extremely surprised" if Reus can train again in
the coming weeks, but Borussia's medical staff and director of sport Michael
Zorc have confirmed the winger is expected back soon.
After the Super cup showdown, Dortmund play fourth division
side Eintracht Trier in the first round of the German Cup on August 22.
That will be their last match before the new Bundesliga
starts when they host Mainz on August 27 and have qualified directly for this
season's Champions League after a year's absence.For
