Jacynta Galabadaarachchi is set to play a key role in West Ham's record-breaking London Derby against Tottenham Hotspur at London Stadium.
The Women's Super League is having a groundbreaking season in England, with derby crowds packing out the Premier League's biggest stadiums.
Manchester City and Manchester United's reason derby nearly-sold out Etihad Stadium and now West Ham against Tottenham is pipped to pass the 20,000 people mark at London Stadium, the first time the Hammers women will have played there.
Galabadaarachchi, who has featured strongly so far throughout their campaign, will likely play a key role. Tottenham are currently one spot below West Ham in sixth, with only goal difference separating the sides so far.
"It'll be a really amazing occasion for us but they are the sort of numbers we're hoping for, which will fill the lower bowl and just a bit above that as well," Sullivan told the BBC.
