There is a different feel to this Class of 2018, though - Southgate and his support staff have managed to instil a positive atmosphere around the Three Lions' camp.

They have been more open and jovial around the media, the players are clearly enjoying themselves in training and there is genuine optimism that the Three Lions can mount a decent campaign - optimism that, for once, might not be misplaced.

It's been all fun and games for England away from the training pitch

They will be forced to shuffle their line-up for the match at the Nizhny Novgorod Stadium, which kicks off at 10:00pm AEST, with Tottenham midfielder Dele Alli not yet recovered from the thigh strain he picked against Tunisia.

"He started training with the rest of the group, then did some more running on his own, so he's progressing really well," said Southgate.

"We're really pleased with where he's at, but he wouldn't be ready for Panama."

Chelsea midfielder Reuben Loftus-Cheek is expected to fill in for what would be the 22 year-old's first start in a competitive international.

Meanwhile, Manchester City winger Raheem Sterling should keep his place despite underwhelming in the Three Lions' opening match.

England can't afford a slip up if they want to top Group G - a win is vital to keep pace with a free-scoring Belgium team which put five past Tunisia last night.

The Three Lions face the Belgians in their final group game in what is likely to be a straight shoot-out to decide which side finishes first and second.
