Jerome Boateng has backed Chelsea striker Timo Werner to "show who he really is".
Signed for £47.5m last summer, the German struggled during his debut season at Stamford Bridge with just six league goals.
But after finishing the season on a high winning the Champions League final, Werner has been backed to thrive at the Euros by his compatriot.
"Timo has changed country, club, playing in a new league," Boateng told BILD. "It is not so easy. Nonetheless, he scored his goals, provided assists, was present, went through a hollow and came out and now he's the Champions League winner.
"For me, it has been a positive season with the usual ups and downs. It makes him bigger and stronger and he learns from it.
"At the Euros, we will see another Timo Werner, a hungry Timo. A Timo with more arrogance, because he has just won the Champions League. It carries you. He will show who he really is."
