It is hard to quantify the impact Sam Kerr has on the Australian soccer landscape.

Beyond the statistics — numbers which by themselves paint an impressive picture of a world class player at the peak of her powers — Kerr is also the talisman for the Matildas, the face of an international advertising campaign and a role model for aspiring players

She also almost single-handedly keeps the code in the news with her performances, which for soccer in Australia, with its many challenges, is of vital importance.

But as is the norm in a global sport, it is only a matter of time before the big players come knocking on the door.

Two years ago, the striker was almost lost to the W-League when French powerhouse Paris Saint-Germain enquired about her services, with Kerr admitting she did not think she would be back in Australia.

"While I was in the W-League last year I was talking to PSG, I was talking to all different clubs," Kerr told Fox Sports in October last year.

"I kind of cut out the W-League. I was never coming back."

Kerr admitted she felt the pressure to "do Europe".

That pressure is again on the 25-year-old, after reports emerged earlier this year that English giants Chelsea had offered the striker a $1 million two-year deal to move to London.

Chelsea offers Kerr more than a big payday

For instance, Chelsea's women's side competes in the English Women's Super League and a domestic cup competition, and will also be aiming to be a part of next year's Champions League, which features the best sides in Europe.

It also goes beyond just the level of competition. Europe remains the cultural centre for global football, and playing there brings a level of prestige which cannot be found elsewhere.

"To have her play in our league is fantastic, but we are also mindful of the fact that maybe she needs to go to Europe," Perth Glory CEO Tony Pignata said.

"There is a lot of interest there as well.

"She has given a lot to Australian football, and if that's her decision going forward we give her our blessing.

"But until that's decided, we're hopeful she comes back."

Glory not giving up on 'face of the W-League'

Kerr is not contracted to the Glory or to the W-League, but has been offered a contract by Football Federation Australia to return as a marquee player.

"We've been speaking with her manager, but we're just letting Sam finish off her [American] season," Pignata said.

"I'd be very sad to see her go, if that's what happens. To replace Sam Kerr is very hard, she is probably one of the best players in the world.

"She has a lot to do with the exposure of the league, exposure of Perth Glory. She's a fantastic player as well.

"She is the face of the W-League, that's an important fact."

Kerr has six regular season matches remaining for her National Women's Soccer League side Chicago Red Stars in the US.

She will then face the decision to return to Perth or explore the many offers she is sure to receive in Europe.
