Statistics show that 37 players moved, planned to move, or had a move pending, either to or from an A-League outfit during the month of January. In a competition of only ten clubs, with rosters limited to 23, that's nearly 15 per cent of the entire playing staff on the move, in just thirty one days.
But whichever way you slice it, there's no doubt the month of January is a disruptive one for clubs, especially with Asian clubs circling, dangling larger wages as bait.
Then, there's the thorny issue of transfer fees.
Central Coast Mariners, undoubtedly the club which has suffered the most, received just $210,000 for the sale of Trent Sainsbury - one of Australia's hottest young properties - to Dutch club PEC Zwolle. Veteran Daniel McBreen, last years golden boot winner, was allowed to move to Shanghai East Asia for free.
The Mariners starting eleven against Roar on Sunday contained only three players who began last years Grand Final - Josh Rose, John Hutchinson and Mile Sterjovski.
The rest (with the exception of the retired Patrick Zwaanswijk), have moved on for a net return of just $450,000. Throw in Tom Rogic, who left for Celtic halfway through the season, and it's around $1million.
Where else in the world could you transfer four full internationals, one who probably soon will be (Sainsbury), plus a golden boot winner for that sort of money?
Perhaps it is no surprise then, that the net spend on transfer fees for all ten A-League clubs during the window, was...zero.
Contrast that to the $1.4 billion spent by English Premier League clubs since the start of the season, and you get some idea of the chasm that exists between here and there.
