Ben Youngs has urged England to improve despite beating France in Saturday's crunch RBS Six Nations clash.
England took a giant step towards the Grand Slam after their 17-9 heroics but Youngs was unhappy with the performance at Twickenham.
The Leicester scrum-half was disappointed with the amount of errors Martin Johnson's forwards made against Les Blues and demanded higher standards across the board for the next game against Scotland.
Youngs said: "A win against the French is priceless, especially against a very good French side that came here to dominate and bully us and they simply didn't do so.
"But some guys are disappointed with their personal performances, me included. We demand high standards.
"There were a lot of us frustrated at half-time and getting a bit angry with each other. I gave the forwards a bit of a rollicking.
"I was running into spaces and there were holes around me and no-one was running off me. It was a little frustrating because you think what the hell are you doing?"
"It is pretty simple. If I run out and the bloke comes to tackle there is usually a hole on my shoulder. We have to make sure our guys start reading that otherwise I will be getting even more frustrated."
Fly-half Toby Flood suggested England's confidence may even have taken a knock by the performance but Youngs claims the team have come on leaps and bounds since losing to a physical South Africa side in the autumn.
"Against the Springboks we got bullied and lost the game. This time we came out on top, which shows we are learning to deal with different game plans and styles," Youngs said.
"It shows we are moving in the right direction because this team wasn't happy with that performance.
"We know we have more to give, we should have closed the game out sooner and scored more points."
