Borussia Dortmund manager Thomas Tuchel has warned his club not to sell star man Pierre-Emerick Aubameyang after rumours of Real Madrid's interest.
Aubameyang is the top scorer in the Bundesliga this season with 15 goals in 12 appearances and has spoken in the past of his desire to play for Spanish giants Real, per French newspaper L'Equipe (h/t Jefferson Lake of Sky Sports).
However, his prolific form has led Tuchel to state that the forward is indispensable to Dortmund.
Per Richard Martin for Reuters (h/t MailOnline), the BVB boss said: "It's normal that 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.
"But my opinion is clear. We cannot achieve our objectives without him. He's an extraordinary player, he makes everyone better."
Earlier this year, the Gabon international revealed a promise he gave to his late grandfather that he would play for Madrid, per Lake.
"In 2014, just before the death of my grandfather, who was born in Avila 100 kilometres from Madrid, I gave him the promise to play one day for Real," Aubameyang said. "It'll be complicated, but this (promise) is anchored to a corner of my heart."
Aubameyang has certainly stepped up his game in the two years since the departure of Robert Lewandowski to domestic rivals Bayern Munich.
After a stellar campaign last season, his goal-laden talents have ensured his stock continues to rise at the Westfalenstadion.
The striker is blessed with pace and trickery and is a constant threat to opposition teams both in and outside the box.
While his versatility is such that he can play anywhere across a front attacking three, Aubameyang has shown he is more effective when being the lead man through the centre.
This season, his cool, calm finishing ability has been complemented by some improving all-round approach play, and at 27 years old, there looks to be plenty more to come from a forward high on confidence.
Tuchel's comments come as Dortmund and Real prepare to meet in a clash on Wednesday that will determine the winner of Champions League Group F.
Both clubs have already progressed to the first knockout stage, but a point for Dortmund would be enough to go through as group victors.
