That would mean Phil Foden keeping his place in the starting XI, and Jude Bellingham likewise - despite both struggling at times in the two games so far.

As Sky Sports News has reported for several days, Southgate has accepted that his experiment with Alexander-Arnold in a central midfield "quarterback" role has not worked, with Gallagher set to replace him as a more orthodox number eight.

The Chelsea player did that from the bench against Denmark in the 54th minute, but he now looks set to make his first start in a major tournament.

There have been calls for Bellingham to be rested, after he showed signs of tiredness in both group games, but Southgate is determined to start with his strongest possible team to try to ensure they top the group, and avoid a last-16 clash with Germany on Saturday.

Foden put in a much-improved performance against Denmark, and it looks like Southgate will resist the temptation to dip into the wide array of wide attacking talent in his squad; Cole Palmer and Anthony Gordon have both yet to get any game-time in Germany.

It's thought Southgate does plan to make a number of substitutions against Slovenia, in the hope of managing the workload of some of his key players. But much will depend on the circumstances of the game.

All 26 players trained ahead of Tuesday's encounter, but left-back Luke Shaw will not feature as his rehabilitation from a hamstring issue continues cautiously.

Rice feels 'safe' with Gallagher by his side in England midfield

Declan Rice is ready to rekindle his midfield partnership with Gallagher with the pair set to start against Slovenia

Rice played alongside Gallagher during his youth career with the Blues and is looking forward to a potential partnership with England.

"I have played with him at academy level, played against him at Palace and Chelsea," he said. "He is a team-mate I would love to have on my team, he works his socks off, you feel so secure and safe in there with him.

"I think he has surprised so many people this year with his ability on the ball, how he breaks forward with it, how he gets into the box, scores goals.

"I think he is a really positive player and he has come on so much over the past few years as well, you can really see that within himself how confident he is.

"Every time I get to play with Con, it hasn't been much, I have really enjoyed it because I know him really well as a guy, I know his family really well and he is a lovely boy and it is another great chance to stamp our mark."
