Chelsea boss Emma Hayes said if defender Cooper, 26, who joined the club in 2017 from London Bees:: "To watch a player fulfil their dream, coming from the place she has, fighting to prove she deserves to be at this level, is one of the reasons I go to work as a coach.

"I’m sad to lose the person, but I’m excited to see the player that I know she can be.’Chelsea Women would like to wish Deanna the best of luck for the future."
