The outgoing Manchester United centre-back believes Roy Hodgson's side should have taken a draw against Uruguay instead of leaving themselves open to the counter-attack late on
Defeats to Italy and Uruguay meant that Roy Hodgson's men were relying on the Azzurri to win their last two games if they were to have a chance of progressing, but Costa Rica's 1-0 victory over Cesare Prandelli's team ensured England go crashing out at the group stage.

"The World Cup would have been a better place with England in it but you've got to earn the right to stay in the tournament and unfortunately for us we haven't done that," he told BBC Sport.
"We were a bit naive in certain situations. The game yesterday [against Uruguay] for instance, when we got back into it at 1-1 we had a chance to get a point, dust ourselves down and say 'right, we're ready for this last game and everything's going to be on this last game'.
"But we didn't give ourselves that opportunity. It was there for us and we just couldn't see it through."
Despite their early exit, Ferdinand does believe that the younger players within Hodgson's squad will learn from the defeats ahead of further tournaments.
The 35-year-old believes the exposure to top-level international football will only be an advantage as the side look to improve going forward.
"The England players can take the experience. When I went to the 1998 World Cup I didn't play any minutes.
"Some of these young guys have had minutes and are going to get more against Costa Rica hopefully and they can take that into the next tournament for us."
