"I have realised that I will not be fit enough to play tennis at the level I demand of myself," said Soderling, 31, to the Swedish news agency TT. Soderling fell ill with glandular fever in the summer of 2011, but he did not realise the seriousness of his sickness and continued to train, although he struggled physically.
