The successful coach believes the titleholders are still the same team that dominated the league last term, and is full of ambition ahead of the second half of the season
The reigning champions currently sit third in the table, trailing leaders Bayern Munich by 12 points, but Klopp remains ambitious ahead of the second half of the season.
"We are definitively no worse than last season, we are just a few points short," he was quoted as saying on the official Dortmund website.
"Our attacking potential is overwhelming, but the 22 goals we conceded in the first half of the season is an unusually high number for us.
"We are very ambitious and we want to play an outstanding second half of the season. Our way of playing will clearly be recognisable again."
