The Celtic boss has been discussing the 22-year-old midfielder.
Deila brought Rogic on in the second half and then praised the Celtic man for adding tempo to his side's game and allowing them to create enough chances to beat Hearts 2-1.
RD: You can see we’ve played three games in six days. We didn’t have the tempo to open them up.— Celtic Football Club (@celticfc) October 28, 2015
RD: Tom Rogic came on and added that and we got our chances.— Celtic Football Club (@celticfc) October 28, 2015
Rogic's performance adds to what has been a good season so far for the Australian midfielder. As for Celtic as a whole, the Bhoys' response to last week's Molde debacle has been an encouraging one.
Deila and co cannot turn back time and change their Europa League position - that remains precarious.
But what Celtic have ensured in the week or so since their European loss is that domestic affairs are not an issue.
The Hoops are now into the last four of the Scottish League Cup and sit top of the Scottish Premiership. For those who feel domestic success isn't enough for Deila, however, that won't help his reputation if Celtic still end up eliminated during the group stages of the Europa League.
