Rafael Nadal at the championships for the first time in three years next week, it will be the Spaniard's foot, rather than his formidable forehand, that will be scrutinised to the nth degree.
Until a few days ago, very few people had even heard of 'radiofrequency ablation treatment' - a procedure which uses heat on the nerve to quell long-term pain.
But it is thanks to that procedure, which the 36-year-old had earlier this month to treat a degenerative condition that affects the bones in his feet, that he is able to turn up at the All England Club ready to target Grand Slam title number 23.
When Nadal rocked up at the Australian Open in January, he had not won a major for 15 months, had been out of action for five months due to his chronic foot pain and admitted that he had considered giving it all up for good.
