Villa chief hopes new man sticks with youth.
Even after a taster of heady European action last night, MacDonald remains undecided to whether he would like to make temporary role more permanent.
The young players he blooded in his two games following Martin O'Neill's shock exit must hoping he stays at the helm.
MacDonald, who bring his Villa side to St James' Park on Sunday, not afraid to give youth a chance, Marc Albrighton, Ciaran Clark, Barry Bannan, Eric Lichaj and Jonathan Hogg can all proudly testify these past few days.
Bannan was the hero of Villa's 1-1 draw with Rapid Vienna in first leg of their Europa League playoff at the Gerhard Hanappi Stadium.
The 20-year-old Scot was teed up for his first goal for the club Albrighton, who again made mark, as in Saturday's seasonopening 3-0 home win over West Ham.
Clark made an impact in centre of defence for that game, while Hogg and Lichaj were given their debuts against Rapid.
Whether a new manager will look so favourably on the emerging crop as MacDonald does remains to seen.
"All the applicants, and I'm sure they are of a high standard and quite a few, will have looked at how played Saturday and again against Rapid," said MacDonald.
"So they will know themselves what some of those players are like, and if they were to ask me then I give them good information, and hopefully a few of them will around the squad.
development if they want to make into the first team.
"There has been a lot of clubs enquiring about them going loan, but at this moment in time, with the uncertainty, it would probably be beneficial for them stay around and see.
"How far they eventually all depends on a little bit of luck, and also the application they put in over the next few years."
Bannan's 12th-minute tap-in Albrighton's low centre gave Villa the perfect start, and although Atdhe Nuhiu hauled Rapid level minutes later, it is MacDonald's side with the advantage ahead of next Thursday's home return.
"You'll have to ask the fans they were happy with me doing what I did, but I was happy with way they performed," added the year-old Scot.
"We got a good result, but it only be the right result if we get into the group stages of the Europa League."
