Roy Hodgson is due to announce his squad for next month's friendly against Denmark on Thursday afternoon and Sunderland winger Johnson suspects if his recent form has not won him a recall, he can forget about the summer.
Adam Johnson: "I have thought about it a little bit more, but I think it all depends on this next squad if you are going to be there or thereabouts and in with a chance of going.
"I have just got to take each week as it comes. It's all a bit up in the air - there are that many players to choose from, people in form, people out of form, injuries.
"There's a long way to go and a lot can happen, but as an England player, you always have half an eye on a World Cup in Brazil."
