I'm a die hard fan. My first account here was named RF20.
Are you a tennis fan? It is my favourite sport.
I am a tennis fan in the sense that I think it is an amazing sport. However the only sport I felt compelled to watch for a long time was football.
That is changing though. I wanna watch more tennis in future (though I missed the best era, don't think Alcaraz, Sinner etc can replicate it). But I like other sports even more. I wanna try watching futsal (the World Cup was just on), volleyball and handball also look excellent, and I love competitive swimming too. However, my favourite second sport would be athletics/track and field. I normally just watch the Olympics but this time I told myself I would keep up with the season too i.e. generally the Diamond League and the World Championships, and I did watch the Diamond League following the Olympics. I know a good amount of the names and faces on the scene now.
I do regret not seeing the big 3 (plus Murray) era of tennis, though. My brother loves tennis (and football) but his favourite is Djokovic. He also really likes Messi too. I always thought Djoko was more like Ronaldo and Federer more like Messi - in terms of style of play I mean, not personality.
I watched Wimbledon all the time in the 90s. I also watched a great video of Del Potro forehand winners recently. He must have one of the best forehands in the game.
