Tennis legend Andre Agassi has penned a letter to Rafael Nadal detailing his admiration for the Spaniard's success in his career. The eight-time Grand Slam champion posted the note online to show his respect for Nadal's phenomenal record on clay at Roland Garros.

The note posted following Nadal's win over Australian Sam Groth in the first round of the ongoing French Open, shows Agassi calling the Spaniard "inspiring'' and "remarkable".

"It took me most of my career to accomplish the herculean task of winning the French Open one time. Watching you attempt to win it for the tenth time is not only remarkable, it is inspiring", Agassi wrote.

"You make me believe in life that anything is achievable and nothing is impossible. Go get em."

Agassi won the French Open way back in 1999 when he defeated Ukranian Andrei Medvedev in a five-set thriller. The American also has an impressive record at the event winning 51 matches while losing just 16; this though is way below the standard that has been set by Nadal.

The world number three has a 70-2 record at Roland Garros since his first appearance in 2005 and is on track to improve that record, beating Australian Sam Groth 6-1, 6-1, 6-2 in the first round of the French Open 2016.

Agassi's letter will be posted at the Nike store in Paris along with hundreds of other tributes for the Spaniard as he looks to win his 10<sup>th French Open title.
