8 great players who are available on free transfers this summer

3. Schalk Burger

Burger could have hung up his boots in 2006 after breaking his neck in a Test against Scotland. He could have retired in 2013 after surviving an illness that saw him at death’s door. Incredibly, he made a full recovery on both occasions. The 36-year-old, who left Saracens this summer, is yet to confirm his retirement and would be thought of as an incredible signing for almost any club on the planet.
