Marco Reus has suggested that there is more to come from Borussia Dortmund as they bid to continue their fine start to the season against Hertha Berlin on Sunday.
Thomas Tuchel's side have won all seven of their competitive matches at the start of his reign, scoring 27 goals in the process.
However, Reus believes that Dortmund can still improve after making such a promising start to the campaign.
"We're now well prepared for our Bundesliga game against Hertha on Sunday," the Germany international told reporters.
"We've found good ways of working together. We haven't reached our full potential yet, but we're on our way there."
Dortmund won both of their opening Bundesliga games 4-0 against Borussia Monchengladbach and FC Ingolstadt 04, respectively.
