St Mirren still looking to strengthen squad
MacPherson has also been linked with interest in another Falkirk defender, Kenny Milne, but it could be further up the field that the Love Street manager is focusing on.
"We have been able to get four new players in fairly early," he told BBC Sport.
"But we are still in the market and looking to strengthen the squad. We still have one or two things in the pipeline.
"We feel that we have got to keep trying to add creativity to the team.
"We are solid, well-organised, we know we can compete at this level of football, but especially at home, we just need to add that bit of creativity."
