The recruitment of the Republic of Ireland international, who scored 18 goals in all competitions last season, means it has been an exciting few days for the Eagles, with Leeta Rutherford and Amy Goddard signing for the club last week.
Manager Dean Davenport revealed his excitement in Palace securing the talents of Khassal and also heavily suggested that there will be plenty more additions to the squad this summer:
"I'm really pleased to have captured the signature of Cherelle. There are some really good players in the Women’s Premier League and Cherelle is at the top of that list. I now feel the time is right to give Cherelle the opportunity to step up and use her qualities at Crystal Palace.
"We are building for a strong team and all being well, we will be looking to challenge for a top half finish - watch this space!"
