The prize is voted for by fellow players and, in his first season back in England, Ronaldo has been nominated for the accolade again after winning it following the 2006/07 and 2007/08 seasons.
Ronaldo is already in esteemed company, with Wayne Rooney, Ryan Giggs and Eric Cantona among a select group of former Reds winners.
And if he is successful this year, Ronaldo will become the first-ever three-time recipient.
Ronaldo’s 18 goals in the top flight ensured he finished third in the goalscoring table, with only Mohamed Salah and Son Heung-min - who shared the Golden Boot award - outscoring our no.
