Chelsea winger Christian Pulisic admits that playing under manager Thomas Tuchel is not easy.
The German coach is known for being very demanding of his players, evidenced by the team's discipline and work rate since his arrival.
However, Tuchel has led the team to Champions League and Super Cup glory in half a season.
Pulisic, who has experience under Tuchel at Borussia Dortmund, admits the boss's rotation of his players can be tough to handle on an individual level.
"It was very tough," reflected Pulisic before their Super Cup penalty shoot out win over Villarreal on Wednesday, per The Metro.
"I felt like I was in my best form and to be back on the bench was extremely tough. When you are in form, you feel good and want to carry on.
"Competition here is fierce. We want to win titles. It is about keeping your head in the right place so if an opportunity comes you can still make a big impact."
