Roy to experiment v Ecuador
England manager Roy Hodgson will field an experimental XI in Wednesday's friendly against Ecuador, with Frank Lampard named captain.
Arsenal's Alex Oxlade-Chamberlain and Manchester United defender Phil Jones are expected to start the match at the Sun Life stadium, while Southampton left-back Luke Shaw could also step in to allow Leighton Baines to be rested.
Addressing the media alongside Lampard, who will deputise for rested skipper Steven Gerrard, after their first training session in Miami, Hodgson confirmed that all 25 players came through the morning unscathed.
"They all played a full part in training and I'm happy that, at this stage, after two-and-a-half weeks of training, we don't have any injuries," he said.
"We have two more preparation matches and I'm hoping we get through those. It would be marvellous to get on the plane to Brazil with all 23 players because, after this Miami part, the two young guys Jon Flanagan and John Stones will leave us.
"There will be changes in the team for Ecuador, no question, but I can't speak in detail because of reasons we often cite. There will be a team meeting tomorrow where we'll talk about Ecuador and I will perhaps tell the team who is playing then."
The squad was forced to abandon their first training session at Barry University on Monday after torrential rains flooded the pitches and forced Hodgson to take his players inside.
It is the start of the hurricane season in the south-eastern part of the US but the England coach hopes the heat and humidity will play a huge part in helping his players acclimatise to such a climate.
"It's warm out there and conditions are very similar to those we will encounter in Brazil," he said.
"In terms of acclimatisation, we couldn't have come to a better place and we are happy with the initial part of our preparations.
"The measurements we've taken in terms of the players' sweat analysis are important. Not all players sweat in same way and they will need different hydration from each other.
"We will be making sure we continue with our tactical work while we are here and building one step at a time."
