Any bias on behalf of the ants, which reside in the United Kingdom, was not taken into account, but this does not worry Mr Nicholson who said he was "forever hopeful" of England's chances of success. The team that starts the match is the one with the most experience, that's one of our assets.
If England beat Panama and Belgium beat or draw with Tunisia then England are through to the last 16.
Panama, meanwhile, are unlikely to see the leaked teamsheet as a great revelation that will overthrow their tactics, and will probably line up as they usually do in a 5-4-1 or 4-1-4-1 and try to snatch a goal from a set piece.
England have been backed to beat Panama on Sunday - by a colony of World Cup-predicting ants.
"I'm relaxed. The team came out three days before the first game and I didn't say anything because it's something we can't control".
Mexico too strong for South Korea
If Germany lose to Sweden in the evening's Group F game at the Fisht Stadium in Sochi then Joachim Löw's side will be out. Son Heung-min pulled one back for South Korea in stoppage time with a spectacular left-foot strike from outside the area.
"It makes sense for us to train early, recover and travel. We need to be compact and limit their space". There is only one ball on the pitch and we're going to fight for it'. We just kept to our game plan.
"The credit goes to the manager and the players we have got because a lot of the players at their clubs never change their style of play in hard situations, they keep working at it and grind down teams", he added. It is a squad of 23 names on the sheet, the next sheet has different players in different positions because we swap people in and swap people out. It's not the job of the media to protect the team.
"We want to play in the style we played coming into the tournament. We've got technically good players, we want them to get on the ball and express themselves and really attack the game like we did the other night [against Tunisia]". "They are the things that are important".
Southgate touched again on the debate over the team-sheet that was pictured in the hands of assistant Steve Holland in training and appeared to show Raheem Sterling and injured Dele Alli replaced by Marcus Rashford and Ruben Loftus-Cheek.
"Obviously any time if we were to give the opposition the opportunity of having our team it's a disadvantage to us", Southgate told reporters, according to FourFourTwo.
