Stefanos Tsitsipas reminisces about his childhood memories

The World No.5, Stefanos Tsitsipas has come a long way.

The young tennis star took a trip down the memory lane, posting a photo of himself with his younger brother Petros, with a heartfelt caption.

"Remembering the times when we would both dream of playing at the Olympics together one day. Fist pumping our way to a Grand Slam final in doubles. Sitting out in the garden chitchatting and revealing our dreams, goals and aspirations to one another. Being true and optimistic. Talking about playing on the big stage and wanting the best for one another. The competitiveness and fire we would show when playing one another at the mini-court we built out of tape in our basement," he wrote.

"The fun we had imitating and impersonating our favorite players, and the overall intimacy we had with tennis from an early age. This was our world! Such nostalgia for these priceless moments. Let’s keep dreaming and chasing the unthinkable bro. It’s cool to be on this together!" Tsitsipas continued.

Last week the “three musketeers"- Stefanos Tsitsipas, Giannis Antetokounmpo, and Emmanuel Karalis hung out in Athens.

On Tuesday (October 27), Tsitsipas will face Jan-Lennard Struff in the first round of the 2020 Erste Bank Open in Vienna.
