Barcelona attacker Alexis Sanchez scored twice as the visitors outplayed the Three Lions, who lost for the first time in a year and did not look as sharp as they had done in their vital World Cup qualifiers last month.
"We didn't need a reality check," the Chelsea midfielder told ITV1.
"We are very aware of the job in hand, we are not on the moon and we are not terrible - we are somewhere in between. We have got a long way to go.
"We need to concentrate on what we are doing, we have got another game against top class opposition on Tuesday and we need to improve."
