Thomas Tuchel expects Pierre-Emerick Aubameyang to produce his very best form when Borussia Dortmund take on Real Madrid on Wednesday.
The Gabon international has said on a number of occasions that he would relish the chance to play for the reigning European champions, having promised his grandfather that he would one day make the move.
Tuchel has little desire to allow the forward - who has scored 18 goals in as many appearances this season - to leave Signal Iduna Park, claiming he brings out the best both in his team-mates and his coach.
He does, however, expect the 27-year-old to thrive under the pressure of wanting to make a good impression in the Spanish capital, especially after he scored in the 2-2 draw between the sides in September.
