Hearts 1-4 Celtic: What Critchley said
Hearts head coach Neil Critchley: "We were excellent first half. Good organisation, good structure, pressed well and created some really good moments.
"You have to take your chances in these type of games, and we didn't. You also need an element of luck and they had it for the first goal. 4-1 looks like a drubbing but I didn't think it was a true reflection of the game.
"We need to bounce back. We're in a relatively decent position in Europe and we need to go and improve if we want to get something on Thursday night [against Cercle Brugge].
"I saw lots of positives tonight; it's important the players feel that."
