Gareth Southgate's only change from the team that started against Tunisia will see Ruben Loftus-Cheek make his full World Cup debut in place of the injured Dele Alli, who is hopeful of being available for the final group game against Sweden.
After performing some exercises with the group, he then continued with some solo work.
The revelation was the first indication the squad had that Raheem Sterling could be dropped after struggling to make an impression in the opening win against Tunisia on Monday and Marcus Rashford could lead the attack with captain Harry Kane.
"Obviously any time, if we were to give the opposition the opportunity of having our team it's a disadvantage to us", Southgate said.
"So of course our media have to decide whether they want to help the team or not".
"I made quite a balanced observation yesterday, which I am told has gathered quite a bit of momentum", said the coach.
Sterling's time may still come but it appears as if Rashford is set to be given the nod by Southgate and he surely won't let anyone down, particularly against a Panama side that are arguably the worst team at this World Cup. "There's no drama for me about it".
England will play in the warmest temperatures they have faced so far in Russian Federation, with the mercury soaring in their next host city.
On Sunday's game, he said England had done "due diligence" on Panama and was not expecting an easy game.
Former England manager Roy Hodgson has claimed that Chelsea youngster Ruben Loftus-Cheek is better than Michael Ballack in his prime.
"So if you could just please help us with that, it would be polite".
