The club is believed to be close to signing Pierre-Emerick Aubameyang from Saint-Etienne but the coach says he is happy with his current squad.Borussia Dortmund coach Jurgen Klopp has played down expectations of a summer transfer frenzy and insisted that he is happy with his current squad.
Mario Gotze left the 2012-13 Champions League finalist for its conqueror in Europe and main Bundesliga rival, Bayern Munich, in a 37 million euro deal, though incoming transfer activity has been kept to a minimum.
Sokratis Papastathopoulos is the only player to have joined the club as of the start of July, though Saint-Etienne striker Pierre-Emerick Aubameyang is believed to be close to joining the Schwarzgelben. Klopp thinks that patience is required from supporters and wants time to build his squad's strength.
"We know how we want to play soccer in the new year. We know our goals," Klopp told reporters. "We can’t achieve everything on the first day. We will take the time that is necessary.
"We are very pleased with the team we have so far. There are no differences (to the preparation last year) but that doesn’t matter, because I rate all [my players] differently."
Dortmund's first competitive fixture of the new season will be against Bayern in the DFB-Supercup on July 2013.
