Messi enjoyed another stellar campaign for Barcelona in 2018-19, scoring 36 goals in 34 LaLiga matches, inspiring the club's title defence and run to the Champions League semi-finals.
Ronaldo's first season at Juventus – who will be known as Piemonte Calcio on FIFA 20 – went as smoothly as might have been expected, with the forward finishing as the club's top-scorer as they claimed an eighth successive Scudetto, though that was not enough to retain his crown as FIFA's highest-rated player.
Neither Ronaldo nor Messi were able to win the Champions League, however, with that honour falling to Liverpool, who have two representatives in the top 10.
Find out who they are and which other players join Messi and Ronaldo in the 10 below.
10. Marc-Andre ter Stegen, Barcelona – 90
Germany international Ter Stegen has developed into one of the globe's most well-rounded goalkeepers after an initially slow start to life at Camp Nou. He is one of three players with a rating of 90, making him the second best keeper on the game.
9. Luka Modric, Real Madrid – 90
Last year's Ballon d'Or winner, Modric's 2019 has not been particularly outstanding, as he has found himself out of the Madrid team a little more due to suspect form. He may be down one rating point from FIFA 19, but he still reaches 90.
8. Mohamed Salah, Liverpool – 90
A crucial part of Liverpool's Champions League winning side, Salah has truly established himself as one the world's primary stars over the last couple of years. He was not even in the top 20 in FIFA 19, however.
7. Virgil van Dijk, Liverpool – 91
The most important player in Liverpool's Champions League success? Until recently the most expensive defender ever, Van Dijk's influence on the Reds is undeniable. That is reflected in the fact he will be FIFA 20's best defender.
6. Jan Oblak, Atletico Madrid – 91
Widely regarded as the best goalkeeper in the world for his quality and consistency, Oblak replaces David de Gea – who had a shaky 2018-19 – as the top-ranked keeper on FIFA.
5. Kevin De Bruyne, Manchester City – 91
Even though injuries have plagued De Bruyne in recent times, robbing him of a chunk of last season, the Belgium star remains one of most highly regarded players on the game, with the City star beginning 2019-20 in ominous fashion.
4. Eden Hazard, Real Madrid – 91
After helping Chelsea to Europa League success, enjoying a generally fine individual campaign as the Premier League's most creative player with 15 assists, he earned his dream move to Real Madrid. He's yet to feature due to injury, but he'll be hopeful of elevating himself to the next level now.
3. Neymar, Paris Saint-Germain – 92
Perhaps a controversial choice to some, Neymar missed a big part of last season through injury and only won Ligue 1 and the Trophee des Champions, as he was also absent for Brazil's Copa America success. Nevertheless, his skill is undoubtable and he comes in at number three.
2. Cristiano Ronaldo, Piemonte Calcio (Juventus) – 93
The best-ranked player on FIFA 19, Ronaldo's rating drops one to 93 despite enjoying a solid season in Serie A. Cynics might suggest Juve's exclusivity deal with FIFA rival Pro Evolution Soccer has something to do with it.
1.Lionel Messi, Barcelona – 94
The world's best player comes in at number one with a rating of 94 after he enjoyed another spell-binding season on all fronts, impressing even though Barca failed in the Champions League.
