Multiple outlets report that USA men’s national team coach Mauricio Pochettino reacts angrily during their match against Belgium. The incidents described involve Pochettino reportedly smashing containers of water bottles after the USA concede their second goal. According to the accounts, his visible frustration comes shortly after the Belgium goal that puts the USA under further pressure, prompting an on-field display of anger directed at equipment rather than players. One report describes the coach’s outburst in more detail, stating that he smashes a container of water bottles in a fit of rage. Another describes the episode more generally as Pochettino taking out frustrations early in the match. Both accounts agree on the timing and the trigger: the second goal conceded by the USA to Belgium and Pochettino’s immediate, physical reaction involving water bottles. The reports do not add additional confirmed information about any disciplinary action or official league response within the shared excerpts.
