The number 10 carries immense significance in football, it's the most famous.
Some of the greatest players have donned the jersey and we always expect them to serve some magic anytime you see them with the ball.
It's one way of identifying a team's best or most valuable player and it so happens they are all either strikers or generally attacking players.
Pele, Lionel Messi, Diego Maradona, Johan Cruyff, Roberto Baggio, Wayne Rooney, Alessandro Del Piero, Ronaldinho, Zinedine Zidane, Neymar...the list is endless.
The number 7 jersey comes a close second behind the number 10. Traditionally, it's associated with wingers and good ones for that matter.
Cristiano Ronaldo is perhaps the most famous with that jersey but the likes of David Beckham, Luis Figo Andriy Shevchenko, Raul Gonzalez, and Franck Ribery also made a name with the number 7 on their backs.
But what happens when top players in clubs are not able to get their preferred jersey numbers because they are occupied?
Mainly players look for options, the closest they can get as they wait for their favored numbers to be freed.
That's where the number 17 jersey comes in for most attacking players. Well, it's not the most famous, but if recent trends are anything to go by, it is equally favored by a number of stars.
If you put 10+7 together, you get 17. Could this explain why the jersey is associated with some best players?
A number of good attacking players have started their careers with the number before eventually shifting to either the number 10 or 7 jerseys.
Cristiano Ronaldo wore the jersey as a youngster for Portugal before inheriting Luis Figo's number 7.
Hazard at Chelsea, Alexis Sanchez at Arsenal, Steven Gerrard at Liverpool, Mohamed Salah at Chelsea just to mention but a few.
They all waited patiently for the stars who donned their favoured jerseys before eventually moving in.
There are some top stars currently donning the jersey. Kevin de Bruyne is perhaps the first to come to mind.
Manchester City's number 10 is Sergio Aguero's while the number 7, which the Belgian wears with the national team, is taken by Raheem Sterling.
Antonio Griezmann at Barcelona, Erling Haaland at Borussia Dortmund and Europe's leading top scorer this season Ciro Immobile have all shone with the jersey.

The jersey might not command the same respect as the number 10 jersey, or even the number 7, but clearly it is significant, going by the players to have won it.
Can it become the alternative number 10?
