"The club knows very well my opinion", added Sarri.
"It's not easy, and I think that we are lucky because we have [Ethan] Ampadu, we have [Andreas] Christensen, we have [Hudson-Odoi], so we are lucky". We have to try to solve the problem.
Chelsea, Arsenal and Tottenham Hotspur are amongst the clubs who are interested in signing AC Milan midfield star Franck Kessie.
Quizzed on the possibility of signing a new forward, he made it clear the responsibility lies with owner Roman Abramovich as he said: "It depends on the board, not on me".
With Olivier Giroud sidelined after suffering an ankle injury in Sunday's win at Crystal Palace, Sarri opted to recall misfiring striker Alvaro Morata. I have to try to improve my players, my team, my offensive phase, or better my offensive phase in the last 20 metres.
"I don't think that's anything new to football, do you?"
Reports suggest that the West London club have cooled their interest in the former Real Madrid player.
Speaking after the game, Sarri admitted that his team need to address their attacking deficiencies, citing their lack of cutting edge in the final third.
Substitutes Cesc Fabregas and Ruben Loftus-Cheek then combined to tee up Morata but Gunn blocked his low shot.
