Pierre-Emerick Aubameyang's repeated tardiness is a problem for Borussia Dortmund, the club's sporting director Michael Zorc has admitted.
Aubameyang is Dortmund's star turn, with 31 Bundesliga goals last season and 13 in 15 games so far this term.
He was, however, suspended for a match last month for "disciplinary reasons,'' and Zorc revealed his poor time-keeping was an issue club bosses were struggling to resolve.
"Auba is a special player ... he is extravagant and a colourful character. That does a city like Dortmund a lot of good,'' Zorc was quoted by Sport Bild as telling Sky programe 'Wontorra-Talk.'
"We have only one problem with him -- that is punctuality. We have to be very clear about that.''
Zorc added: "This crept in last year, that he often arrived too late. His pal [Ousmane] Dembele [who moved to Barcelona in the summer] was right there.
"Then, as a club, you have the problem of how to handle it. I don't believe that we can completely get rid of it, but we can handle it fine.''
Aubameyang's scoring form has seen him repeatedly linked with a host of clubs across Europe and speculation about his future will no doubt surface again in January.
