Having made a name for himself in Non-League football, McDonald initially joined Gillingham on-loan from Norwich City in 2010 and made a big impact.
The striker scored 25 goals in 41 appearances that prompted a permanent move to the Sky Blues. He spent two years at the Ricoh, scoring seven goals but couldn’t replicate the form of previous seasons.
McDonald would join the Gills again on loan before making the switch permanent in 2013.
