The 52-year-old made a sensational start as coach of the Equatoguineans, taking the 2015 Cup of Nations hosts to the semi-finals.

The 52-year-old made a sensational start as coach of the Equatoguineans, taking the 2015 Cup of Nations hosts to the semi-finals against all expectations.
Finishing fourth was particularly impressive as Becker got the job just a couple of weeks before the tournament having been in charge of the national women's team.
