Under Armas, Toronto (1-8-2) has lost six straight and is winless in seven. Its defence is broken and it's clear that Armas' bid to change the team's style of play, long established under former head coach Greg Vanney, to an aggressive pressing approach was an uncomfortable fit.
Assistant coach Javier Perez will lead the team Wednesday against New England on an interim basis. After Wednesday, Toronto does not play again until July 17 against Orlando City.
Club president Bill Manning, echoing the view of most fans, said the team had become "very difficult to watch." Never more so than Saturday, which marked largest margin of defeat in club history.
