Former world No. 1 Andre Agassi didn't back down while describing the talent of rising star Nick Kyrgios.
23-year-old Kyrgios is widely considered to be one of the most talented players on the Tour.
The Australian has captured four ATP titles so far in his career.
Kyrgios, ranked at No. 24 in the world, reached his career-high ranking of No. 13 in 2016.
The Australian has played only four tournaments so far in 2018 -- with the last being Houston in April.
Injury-plagued Kyrgios has overcome an elbow injury and is now set to play at this week's ATP Stuttgart.
"I think he's one of the best talents to step on a tennis court,” Agassi said of Kyrgios.
"I think what he does with it (talent) is a function of investing in his body and getting that right because he’s too young to be worried about this (injuries).
"Making sure he does that going forward is important because there's a lot of wear and tear over the years.
"And then hopefully find someone (a coach) who can give him some great guidance on how to fulfil that talent, somebody to work with, you know, is also important.
"There's too many things that make up who a player is but, man, if you put the way I think on a tennis court into Nick’s ability, I feel like you could have four game plans."
