But it could have been so much worse for the Italian if Eden Hazard had not rescued a point for the hosts with a stunning strike in stoppage time.
Raul Jimenez had earlier put the newly-promoted side in front and they were on course for a shock victory until the Belgian popped up.
In truth, it was Sarri’s Wolves counterpart Nuno Espirito Santo who might have been more annoyed after watching two points snatched away right at the death.
But Sarri was clearly not happy with what he had seen as he appeared to forget the post-match ritual of shaking the hand in his opposing manager.
Sarri leapt up from his seat in the dugout right on the final whistle and looked to be aiming for the dressing room.
However, Espirito Santo caught his attention before he made his way down the tunnel and the Italian duly smiled and shook his hand.
The result was another blow for Chelsea who are desperately trying to finish in the top four.
Sarri insisted his side were unfortunate not to get more from the match after watching his side spurn a number of decent chances.
“We were a bit unlucky because we conceded the goal in their first situation inside our box after 55 minutes,” he said.
“We need to move the ball faster and play one or two touches not five or six like today so we have to do better when we face a team that doesn’t want to play.
“It is very difficult to play against 10 opponents in the last 25 metres.
“They [Wolves] were not organised, they defended very low, they didn’t need any organisation in that case.
“We tried to change with [Ruben] Loftus-Cheek because he is a good presence in the opposing box and [Callum] Hudson-Odoi because to have someone able in the one-on-one situation is very important.
“In the last 20 minutes we played a new system, 4-2-3-1.
“For Jorginho it is very difficult to play when the other players don’t have movement without the ball. When I decided to play 4-2-3-1 Jorginho was not suitable.
“In the last minutes we were losing so we have to accept the result. We missed a very great opportunity today but we have nine opportunities.”
