Chelsea ace Christian Pulisic admits he's frustrated not finding a place in manager Thomas Tuchel's starting XI.

Former victory over Real Madrid in midweek, Tuchel opted to play a front three of Mason Mount, Timo Werner and Kai Havertz, leaving the American on the bench.

And the 22-year-old is less than pleased with the German, who coached him when the two were at Borussia Dortmund.

"Very frustrated. Yeah not much else to say," said Pulisic on his lack of playing time.

"I wanted to play from the beginning as I always do.

"I've had to continue to prove myself over and over again. But as always I just reach out to God and He gives me strength. With that behind me nothing can stop me really."

Tuchel also said, "Christian got a bad message for him today.

"It was a very tough decision but I'm very happy that Christian turned his anger around into positive energy for the team, helped the team and assisted the decisive goal. So big credit to him."
