Aston Villa parted company with Tim Sherwood at the start of the week.
Sherwood was dispensed of as Villa boss at the start of the week, after a disastrous series of results left the Midlands outfit sitting at the bottom of the Premier League table.
However, despite their poor form, MacDonald says that Villa’s squad are still disappointed that Sherwood has left, and admits they are very low on confidence at the moment.
“Confidence is a big issue. Nobody likes being bottom of the league," MacDonald said.
"The players are hurting for Tim but we can't wallow in self pity."
Villa’s low morale was highlighted on Wednesday evening, as the side crashed to a 2-1 defeat against Southampton in the Capital One Cup.
That result was Villa’s fifth defeat in a row, and their poor form has become a serious concern.
Certain members of the Claret and Blues’ squad have expressed their disappointment at Sherwood’s dismissal on social media this week, with Jack Grealish and Gary Gardner both taking to Twitter to publicly air their disappointment.
It means that the whoever Villa’s new manager is, he has a huge job on his hands, with the side’s next match coming against an in-form Tottenham Hotspur side on Monday night.
