You'd have to ask the club.
Sarri has repeatedly spoken of his frustration at inspiring his players.
Assistant Gianfranco Zola appeared to be the one leading the session while Sarri was involved in a deep discussion on the touchline with captain Cesar Azpilicueta.
"I didn't see my football [against City].
That's what I'd say".
But with no physical presence at the club, it makes it even harder to read the Russian's intentions in Sarri's case. I am anxious about the performance but my job is always at risk so I am not anxious about the club. At the beginning [of the season] it worked.
"Bookmakers are not always right for starters, so I wouldn't get excited about that". So now we need only to understand the reasons why at the moment it isn't working.
"I know exactly what he wants to do", he told a news conference. Sarri's post-match suggestion at the Etihad Stadium, delivered to his country's media, that he "never hears" from Abramovich was apparently not considered as a slight against the owner. It is not easy'.
Chelsea hardly had time to take stock before they conceded again, with Gundogan slotting home a neat shot from the edge after a poor clearance from Antonio Rudiger.
In November, days after signing a five-year contract extension, Sarri criticised N'Golo Kante for his role in the loss to Tottenham.
They next face Swedish side Malmo in their Europa League round of 32 game, a tie they should be expected to win.
Former Chelsea captain Frank Lampard is the bookmakers' favourite to become the next permanent boss if Sarri is shown the door.
In his first stint as a manager, Lampard has earned plaudits for his work at second-tier Derby, who are in contention for promotion from the Championship.
Jose Mourinho, sacked by Manchester United in December, is out at 12/1 for a return to Chelsea for a third spell.
Last season was the first time in his career that Aguero was voted into the PFA team of the year, having been omitted in favour of players such as Romelu Lukaku, Daniel Sturridge & Jamie Vardy in previous seasons.
Patience is hardly one of Roman Abramovich's virtues and the Chelsea owner's fury at this witless, spineless surrender will probably have been amplified by the reopening of old wounds given the manager who inflicted the club's biggest defeat for 28 years was the one he coveted above all others.
