Pierre-Emerick Aubameyang has spoken out following a terrible start to the new season for predicted title challengers Borussia Dortmund, insisting improvement is needed at the back.
After seven games, Jurgen Klopp’s side are 13th with just two wins.
Dortmund are 10 points behind their rivals Bayern Munich who are unbeaten this season under Pep Guardiola.
The Gabon International, who has been speaking to the Bundesliga official website revealed: “We need to be more compact and find a better balance between defence and attack.
“We know that we're always good for a goal and if we can be more solid at the back, then we're going to be hard to beat.”
A key reason why Dortmund have made such a sluggish start to the new season has been down to their extent of injury problems. Marco Reus, Nuri Sahin, Ilkay Gundogan, Henrikh Mhkitaryan and Jakub Blaszczykowski are all missing.
“There's no hiding that this is a problem because we've had to do without numerous players for weeks. But a club like Borussia Dortmund doesn't have the right to hide behind excuses.
“We know how things are and, even if we have lots of problems, we've got to deal with it and look for the best solutions.”
Over the summer, Klopp had to make numerous acquisitions to make up for the loss of their prized striker, Robert Lewandowski who is now enjoying a fruitful spell with the Bundesliga champions.
Losing Mario Gotze the year before has also been a scaring factor for the club who are looking to challenge for the title once more after finishing as the runners up for the past two seasons.
In return, Klopp increased his attacking options by bringing in the Serie A top scorer, Ciro Immobile and former Hertha Berlin striker, Adrian Ramos.
Just before the transfer window closed, Klopp was able to lure Shinji Kagawa back to the Westfalenstadion after an unhappy two year stay at Manchester United.
Despite the additions, the players, in particularly the two new strikers, have failed to gel and after a long pre-season mixed with post World Cup tiredness, Dortmund have been one of the worst affected sides.
On the opening day of the season, Klopp and co were blown away by an explosive Bayer Leverkusen side who scored the quickest goal in Bundesliga history.
This was later followed by a 2-0 defeat away at FSV Mainz 05, a 2-2 draw with fellow strugglers VfB Stuttgart and a 2-1 defeat in the derby of the Ruhr against FC Schalke 04.
Last weekend, Dortmund fans experienced a new low as Pierre-Michel Lasogga fired past Roman Weidenfeller to give SV Hamburger their first win of the season.
Despite their poor results in the Bundesliga, in the Champions League, Dortmund have been a different outfit and more noticeable to the side people have grown to admire over the years.
They dismantled Arsenal in their opening group game firing 23 shots at the Gunners goal in their 2-0 win and they then followed this up with an impressive 3-0 victory away in Belgium against Anderlecht.
