So, this final (not in terms of the tennis played, this was far better) reminded me of the 1988 Wimbledon final (not the fa cup) between Edberg and Becker
Becker was the two time champion (although he wasn’t the reigning champion, as he’d gone out in the second round in 87 to a shock defeat to Australian Peter Doohan who sadly passed away a few years ago)
Becker took the first set and was expected to go on comfortably to win, but Edberg took the second set in a tiebreak and went on from there
The other final that it reminded me of was 2011 Wimbledon final, between Nadal and Djokovic (which Djokovic won in four)
Slightly different as despite a wobbly third set, Djokovic just played Nadal off the court where as Sinner I think had to produce a more controlled performance slowly turning the screw and building up more confidence.
Nadal was a two time winner, and Djokovic playing in his first Wimbledon final
