Rafael Nadal looks to celebrate his 36th birthday on Friday by reaching a 14th French Open final which by his own admission could be the last of his record-breaking career. 

Nadal, the 13-time champion, faces Germany’s Alexander Zverev, but is clear his chronic, long-term foot injury has put him on borrowed time. “The last three months and a half for me, the only thing that I can say is haven’t been easy,” said the Spaniard after his epic four-set win over old rival Novak Djokovic in the quarter-finals.  “But I have to keep going.”
