First, Petke had a squad and he underachieved. When you have guys like henry, olave and cahill on your team than your expected to win at least, open cup, champions league, MLS or the supporters shield every season. In his last season he flopped.
Second, petke acts like a child and has a terrible temper. How many times does he have to get suspended? He gets paid to manage not being suspended
Third, using a slur multiple times is not cool. He is supposed to be a leader on the team. How can an organization have a leader that thinks its appropriate to use that language. Its embarrassing.
Henry was in MLS for 5 seasons. In first three seasons he won no major trophies and lost in Conference QF and SF twice. His two seasons under Petke, where he was at the VERY end of career, he won first major trophy and also reached Final of conference for the first time. So, even Henry did significantly better under Petke in his last two seasons, when he was older, then previous three seasons.
As far as acting like a child and a slur - yeah he cursed at a referee. I heard the word he used many times, he was just trying to put down/curse the referee for helping another team, that's all this was, no more and no less. Yeah, he is a former player, tough as nails, and let's not pretend he is coming from background of some PR department in an accounting Firm. He served a suspension given, and that should be the end of it. He does know his soccer though, and proved to be one of two best coaches ever along with Marsch for Metro in just two seasons, plus delivered good results for Real after. And we need to get some results for this team, that's really all that matters.
