Shrewsbury caretaker-boss Michael Jackson said he will do the job as best he can after seeing his side go down 3-1 at Swindon.
Previous boss Graham Turner resigned this week and former defender Jackson, on the coaching staff since retiring as a player in 2010, has been placed in temporary charge.
Swindon's new striker Michael Smith, who signed from Charlton this week, opened his account after just 30 minutes when he latched on to Yaser Kasim's cross to divert past visiting keeper Chris Weale.
The striker then sealed the win in stoppage time after substitute Nile Ranger had put the Robins back in front following Paul Parry's equaliser.
Jackson, whose side are in the relegation zone, said: "It is a really cruel way to lose the game as we played so well in the second half.
"We did well to get back into the game and I thought we would go on and win it, but their substitutions changed the game.
"I am very proud of my players for their effort after a difficult week.
"They couldn't have given me any more and I am sure they will continue to do well.
"I've worked the last three and a half years coaching the team and the reserves.
"All I will say is that I'll do my very, very best to make sure I do what I'm good at."
