That classless and stupid tweet by his son, and the fact Klinsmann had 23 slots where he could have included Donovan and several younger players sounds like there's some ego or old grudges involved rather than objectivity.
Sounds like the son was projecting some insider (inside the family) animosity. And Klinsmann's blather and excuse making for his son is beyond absurd.
I agree what his son did was devoid of class. There probably is some animosity between the two. Maybe a US player will get “hurt” and Donovan will join the team.
If the US gets out of the group, Klinsmann will get praise. If they don’t, the questions will be flying about his decisions.
