Big games mean big crowds.

The Arsenal fans are currently singing away while the players warm-up.

Chelsea fans were here when I arrived two and a half hours before kick-off, waiting to greet the team outside the players' entrance.

There's a big rivalry between the teams and that has transpired off the pitch to the fanbases.

Should be a great atmosphere at Kingsmeadow!

Pernille Harder has been involved in nine goals in her last six home WSL appearances for Chelsea (4 goals, 5 assists), averaging a goal or assist every 42 minutes across these games.

The forward, alongside club captain Magdalena Eriksson, is leaving the Blues at the end of this season.

Chelsea have lost nine WSL matches against Arsenal, three more than they’ve lost against any other opponent.

The situation is clear for Chelsea today.

Win and they have a finger on the WSL trophy. They then just need to wait for the outcome of the Manchester derby later and if United fail to beat City, the title is Chelsea's.

A fourth successive WSL crown and a sixth in total is up for grabs. Chelsea will not want to lose this.

Arsenal, meanwhile, need to secure third place for qualification to next season's Champions League.

They cannot confirm it today but a victory will go a long way in doing so because they have a far superior goal difference compared to City.

Chelsea took a two-point lead at the top over Manchester United after they won their game in hand at West Ham on Wednesday.

The equation for the Blues is simple. If they win both of their remaining games this season, then Emma Hayes' side will seal a third straight domestic Double having already beaten United in the FA Cup final.
