アレクサンダー・ズベレフさんのインスタグラム写真 - (アレクサンダー・ズベレフInstagram)「Thank you very much David for showing me what it really means to be a top player and to really know how much work and professionalism it takes to be at the top. As I said I have the most respect for you as a player and as a person since the first time we played in my hometown Hamburg back in 2014 where you left me absolutely no chance. Believe it or not it was the best present you could have given me. Showing me what level a top 5 tennis player has and more importantly what level you have. I’m absolutely honored to have shared the court with you on many occasions and also for your last ever professional match tonight. Thank you for everything David. The tennis world will miss you #thankyouferru」5月9日 8時08分
