I say delete the title. It is error ridden from the start or click-bait.
"considered great"? Pleez.
Just ask his peers and other tennis legends what they think.
I didn't think he would win 2 in a season again and be number 1 after the struggles of 2015 and 2016. The only thing I knew was that he was too good to not win at least one more Slam before retirement. Didn't think he'd have such a great season. But then I didn't think Federer would either especially after getting injured last year. I'd feared it could be the end of his career. Very happy to be proved wrong by both players.
