Toni Kroos is one football superstar that's achieved almost everything every footballer can ever dream of. Apart from not winning the Balon D'or, the German international have won every trophy that a professional footballer can ever win including the FIFA World Cup and six UEFA Champions League titles. For a player of his age and current fitness, retiring from the beautiful game of football at this time was very surprising but because we can't question his decision to have quality time with his family, I think we all should respect his decision.
The German international is currently with the national team at the ongoing UEFA Euros Championship but will be quitting from professional football after the European championship. Hopefully he comes back in the future either as a football manager or in football administrative positions.
If he's really retiring from anything football then I didn't see him coming back again as a player but rather could back as coach or take any football related task.
Indeed Toni Kroos is a player I admire such in the final field of especially during his stay at Bayer Munich ,his incredible performance and contribution to the team's mid field would never be forgotten when it comes to football.
