Former Brisbane Lions captain and premiership star Jonathon Brown has called for a complete overhaul of the club after the sacking of coach Justin Leppitsch (pictured).

Despite having a year left on his contract, Leppitsch was sacked on Monday following the clubs dismal capitulation at the hands of St Kilda on Sunday.

The club is now on the hunt for a new coach and Brown says the lack of unity throughout the club is a problem that needs to be dealt with before a positive change can occur.
