For those who have never heard of him, he was an Italian footballer who played for seven different clubs in his career, played more than 50 times for Italy and was a prolific goal-scorer from 1991 to 2012.
But many saw him as a limited footballer who just happened to turn up in the penalty box in the right place at the right time.
Inzaghi is probably most well known for ''being born offside'', a quip that was labelled on him and stuck with him in his later years.
And Inzaghi did stray into offside territory more than most.
But many times he got away with it.
Well, in rugby there are dozens and dozens of Filippo Inzaghis running around the fields every week - just constantly offside, and oblivious to that very fact.
Offside play is continually ruining the game at all levels in the 15-man game.
Players are just offside all the time - at rucks, at lineouts, at penalties, at scrums.
It has been happening in rugby ever so slowly over the years but it appears to be reaching crisis point this year.
Teams just live offside. Players are nowhere near the hindmost foot at any breakdown.
A breakdown - of which there must be at least 200 in a game - has the defending side line up to make tackles.
The defensive players who stand right beside the breakdown in a line are offside - not by a lot, but still offside.
Then going further out into midfield and the next set of defensive players are well offside. By a long way too. That is why the ball hardly gets to the winger these days from the breakdown. Cheating, defensive players do not let it get there.
Everyone is in love with rush defence these days and it seems to be working for many teams.
The British and Irish Lions set the trend for this with their defence on their tour of New Zealand a couple of years ago - the fact is they were offside the entire tour.
Of course, rush defence is going to be working as most sides start well ahead of where they should be standing on defence.
It is quite simply really - a person is going to win a 100m race if they have a 10m start and that is how much of an advantage in context a defence has in many games these days.
There has been plenty of comment about the struggles of New Zealand Super Rugby sides this year but offside play has plenty to do with that. Players getting the ball just have no time to weigh up options, attack and throw a decent pass.
Every team is as bad as each other in Super Rugby while internationally the likes of England and Ireland lead the way.
Referees still blow penalties for offside during games but need to blow more. Sure, they are hard to rule on but needs must and all that.
Doesn't the whole competition and the sport as a whole need a round in which the referees just blow every offside they see?
It may lead to 30-plus penalties a game but if it gets the defence back onside then it will be well worth it.
