The Three Lions will face Colombia in the round of 16 on Tuesday evening, but Angel is not convinced that his country's upcoming opponents have been put to the test in the group stages.
"For the English national team, there has always been a huge amount of pressure to perform in these big tournaments and in the last few years they haven't been able to live up to the expectations," he told reporters.
"Having said that, I don't think the pressure on these players is as much as it was on the so-called 'golden generation'. Not having and not feeling that pressure I think has helped a lot.
"Gareth [Southgate] has managed to bring a young group of players and in a way they have been performing with a lot of freedom. They have the top scorer of the tournament, they've been playing some good football. But they haven't really been with a team that has tested the squad as much as they'd like to."
The winner of Tuesday's fixture will play either Sweden or Switzerland in the quarter-finals of the tournament in Russia.
