Borussia Dortmund boss Thomas Tuchel says the club cannot afford to sell striker Pierre-Emerick Aubameyang to Real Madrid.
In February, Aubameyang shed light on his promise to his dying grandfather that he would play for Real one day, although he later insisted they were not the only club he would consider as his next move.
But, speaking ahead of Dortmund’s Champions League trip to the Bernabeu, Tuchel reiterated the Bundesliga club’s stance on Aubameyang’s future.
“It’s normal he wants to play at Real Madrid one day, any player with his talent would like to play at one of the best teams in the world,” he said.
“But my opinion is clear. We cannot achieve our objectives without him. He’s an extraordinary player, he makes everyone better.”
Real and Dortmund are battling to finish top of their Champions League group but both have already qualified for the knockout stage with one game remaining.
Dortmund lead Group F and are two points ahead of Real, who must win to finish top.
