Ron Rivera angrily hit out as suggestions he was not an enthused as Washington Commanders owner Daniel Snyder by the signing of quarterback Carson Wentz.

In the wake of Thursday's 12-7 win over the Chicago Bears at Soldier Field, coach Rivera was in fiery form at his post-game press conference, eventually calling a halt to proceedings himself.

ESPN this week quoted an unnamed source as saying that the signing of Wentz in a March trade from the Indianapolis Colts was "100 per cent a Dan move".

Wentz came into the Bears game carrying a bicep injury, managing only 12 of 22 passes for 99 yards with no TDs.

However, Rivera wanted to make it clear that his own role in the signing of Wentz was integral to the trade going ahead.

"Everybody keeps wanting to say, I didn’t want anything to do with Carson," Rivera said.

"Well bull****. I'm the f****** guy that pulled out the sheets of paper, that looked at the analytics, that watched the tape when we were in Indianapolis.

"That's what p***** me off, because the young man doesn't deserve to have that all the time. I'm sorry, I'm done."

The expletive-laden torrent from Rivera followed an assessment of how the team's 1-4 start had been wearing on his players.

Finally getting a second win, after losing four straight games, came as a relief to Rivera, prompting him to unload.

Brian Robinson Jr scored the decisive touchdown, two months after being shot in the knee and glute in an attempted carjacking on August 28.

"Honestly it's been hard. It really has. You lose four games in a row and everybody wants to get on you," Rivera said.

"They've played their a**es off. They've played their a**es off for everybody. They come out, they show up, and they work hard, they don't complain.

"They hear all this stuff and they've got to deal with that. I respect them for that because they're resilient."
