The former Manchester United defender says other issues - including who is captain and how the dressing room reacts to John Terry's possible inclusion with his race-row court case looming just days after the finals end - have left England in a mess.
He said: "There's something brewing at the moment. There are situations still not being dealt with. There are player situations going into the tournament, there are manager situations.
"It's going to come pretty quickly. It's April next week.
"There's manager, there's player, there's captain, there's (the John Terry) court case, it's not going to go away.
"And the FA at this moment are in a difficult position as always. If they actively go in there now and do something then it will be like a bull in china shop.
"But I do feel the vultures are circling. The England manager has started being mentioned again this week.
"We are going into a tournament - who is taking the team, what tactics are we going to play, what principles?
"The end of the season is four weeks away. They say they are going to wait until the end of the season - that's May 13 and I think they should make their decision as soon as possible."
