Constant defender Riviere was recognised for her contributions in the direction of clear sheets within the WSL wins over Tottenham Hotspur and Crystal Palace, plus a superb help for Terland in north London.
However there was a transparent winner within the ballot.
After a number of days of voting, Terland got here out on prime with a 54 per cent majority, profitable the award for the primary time in her flourishing United profession.
Riviere completed second on 24 per cent, adopted by Griffiths on 22 per cent.
