Chelsea boss Thomas Tuchel had nothing to say regarding striker Pierre-Emerick Aubameyang's debut.
The Gabon forward started for the club in the Champions League against Dinamo Zagreb.
However, the Blues lost their first group game in the early kick-off on Tuesday.
Asked if Aubameyang was up to par on his debut after signing from Barcelona, Tuchel was coy.
He stated: "I will not talk about individuals today. We play as a team, we lose as a team. That's what it is."
Chelsea struggled in Croatia and lost to a solitary Mislav Orsic goal on the counter attack.
