Mourinho left himself exposed to the risk of sanctions from the Football Association after being sent to the stands for kicking a water bottle during United's 1-1 draw at home to West Ham United on Sunday.
Having picked up 20 points from their first 13 games, United have made their worst start to a league campaign since 1989-90, but Jonessaid Mourinho's latest outburst was not a sign of frustration.
"No, I think that's just passion," said the England international. "I like to see that from anyone -- players, staff. It's passion for the game and a willingness to win.
"We all want to win just as much as each other. We just need to stick together, keep training well, keep creating chances and we will get the goals."
Mourinho, 53, was angry after referee Jonathan Moss booked United midfielder Paul Pogba for diving mid-way through the first half.
It was the second time Mourinho has been dismissed this season after he was sent to the stands at half-time of United's recent 0-0 draw with Burnley, which landed him a one-match touchline ban.
Mourinho also received a fine earlier this month after discussing Anthony Taylor's suitability to referee United's league game at Liverpool.
