An international defender should be able to defend. Johnson is a poor defender. To add to that, he does not look fit enough.
As for Parker, he is an extremely limited footballer. The most flattering thing I can say about him is that he is a pest to the opposition. However, at international level you expect a middielder to have a bit more in his locker. His passing is poor, he does not read the game very well, he is not a goal threat, is ineffective at linking defence with the attack and he appears unable to create anything. We may as well replace with a road hump.
Saying that, I thought he played as well as he can expect to against France, even though he was not close to being one of England's best players. I'd rather Jones playing in midfield as it would add a bit of pace and drive to the team.
