The Silkmen are still coming to terms with the sudden death of midfielder Richard Butcher, 29, last Monday.
While Simpson admits Butcher's loss will be keenly felt, he says a new defender and striker are top of his wish-list.
"We are certainly looking to bring in at least one or two new faces," said Simpson.
"Clearly the events of last Monday made it very difficult to focus on that but I am hopeful we might be able to see some movement this week, failing that next.
"Ideally I would like to bring in one more defender and of course a goalscorer."
