Borussia Dortmund have urged star striker Pierre-Emerick Aubameyang to be careful of his utterances after admitting he could leave in the summer.

The Gabon striker said earlier this week that he needs to leave Signal Iduna Park to progress his career.

However, Aubameyang's comments have not gone down well with BVB's hierarchy and sporting director Michael Zorc who said he has advised the prolific forward to stop giving interviews.

"We have had a brief meeting with Aubameyang and have advised him to give fewer interviews about his plans for the summer and focus more on the race for Champions League qualification," Zorc told Westdeutschen Allgemeinen.

"We have a great relationship with him, but we had to do something to show our focus is on the sporting aspect of the game."

Aubameyang has scored 16 goals in as many Bundesliga appearances for a Dortmund side that sits fourth in the table, one point adrift of third-place Eintracht Frankfurt.

Dortmund host RB Leipzig, who are in second, on Saturday.
