But the Stamford Bridge icon was replaced by Tuchel, who Pulisic has fond memories of due to their time together at Borussia Dortmund.
“I remember making my debut under him and it was a really exciting time,” Pulisic said earlier this month.
“I had to fight my way into that team because it was a very strong team, and being a young player I had to work extra hard.
“The manager trusted in me and most importantly gave me chances to play, so I am grateful for that. He definitely helped me as a young player and I only have good memories of that time.
“We had some success at Dortmund together, and it’s been good to see him again and work with him once more.”
