7. Juan Martin Del Potro
The mighty Argentine, The Tower Of Tandil, Juan Martin Del Potro has always been a powerhouse of talent. After a difficult start to the year, Del Potro picked up the pieces by reaching the semi finals of the U.S. Open - beating Federer on the way.
Flaunting his lethal serve and deadly forehand, the Argentine posed a threat to many top players in 2017 and will likely continue doing that next year. Bulldozing inside the top 10 should not be much of an issue for Del Potro if he manages to stay healthy and devoid of injuries.
