The Blues confirmed the signing of the 20-year-old American from Borussia Dortmund on Wednesday, with the forward signing a five-and-a-half year deal and spending the rest of the season on loan in Germany.
“I am not in charge of the market of course, I have to think about my matches, I have to play every three days so I can only say my opinion to the club."
Sarri's revelations shouldn't come as too much of a surprise, he has repeatedly stated he is not interested in transfers and only wants to work with players on the training pitch.
He was fired as a head coach, a growing trend in modern football, but Chelsea still operate without a Director of Football following Michael Emenalo's departure to Monaco.
Director Marina Granovskaia is responsible for the transfer side of Chelsea for the time being.
When asked if he had asked for more players, Sarri said "No I sent them my opinion if they want to improve the team."

On the draw, Sarri thought his side played well until the final third of the pitch and reflected on the difficulties with so many players out injured.
Chelsea came into the game without Pedro, Oliver Giroud and Callum Hudson-Odoi, and lost Willian in the first half.
"I think we played well for 80 minutes, then in the last 20 minutes we were in trouble. We had four or five goal opportunities but sometimes if you want to have a lot of opportunities you have to score the first goal.
"We did not move the ball very well and we need to improve. We were playing without important players like Pedro, Willian after 30 minutes, Callum Hudson-Odoi was out. On the bench I only had one offensive player Loftus (Ruben Loftus-Cheek) and he is not very well at the moment with back trouble."
