Hasan Salihamidzic has overseen some big signings in his time as Bayern Munich sporting director - Alphonso Davies, Lucas Hernandez and Leroy Sane among them - but none have made quite such a first impression at the contract table as Dayot Upamecano.

"When we sat in my office to sign the contract, Dayot put the pen to one side and said, 'Right, now I've signed the contract, I want to make a little speech'," Salihamidzic revealed at Upamecano's official unveiling as a Bayern player on 13 July.

"Then he explained how proud and happy he is to be at Bayern. I've never experienced anything like it. We were all really surprised - by his command of German, too. It's exactly what we expect and need from him. He needs to be loud with his instructions out from the back on the pitch."

Upamecano switches to Bayern on the back of a formative stint at RB Leipzig, whom he joined from Red Bull Salzburg in January 2017. The 22-year-old defender has gone on to make 112 Bundesliga appearances, including 57 under new Bayern coach Julian Nagelsmann. He was also part of the Leipzig team that reached the 2019/20 UEFA Champions League semi-finals, and has earned three senior international caps for France.

"Dayot doesn't need a long transition period," Salihamidzic continued. "He's here to deliver good performances. He's strong in the tackle, tough, has a good passing game and has the advantage of already knowing the head coach. He knows his leadership qualities will be called on from the get-go."
