Arsenal striker Danny Welbeck "wasn't worried" that he had given away a penalty in the goalless Carabao Cup semi-final first-leg at Chelsea.
Welbeck's challenge in the penalty area on Cesc Fabregas was referred to Video Assistant Referee Neil Swarbrick by Martin Atkinson but after a lengthy delay the decision was no penalty.
Welbeck told Sky Sports: "I didn't know the VAR was actually looking at that incident. I knew I cleanly got the ball so I wasn't worried at all.
"I could see him (Atkinson) talking to somebody in his ear but I got the ball clearly so I wasn't worried."
Calum Chambers added: "You're aware. You can see them talking in their ear but it's one of those things, we'll get used to it."
Arsenal boss Arsene Wenger, who confirmed that Francis Coquelin has completed a move to Valencia, said of the VAR incident: "What I was worried about was that it took too much time.
"I thought maybe they were not sure that it was not a penalty so they looked at it again and again and again."
