Given Tuchel's job description has been underlined as an 18-month trophy quest, will he focus on experienced players he knows well to win now? Interim Lee Carsley's preference was to experiment with youth and prioritise the long-term development of the squad.

England's established centre-back pairing of Harry Maguire and John Stones are both injured, with a younger crop of centre backs such as Marc Guehi, Levi Colwill and Jarrad Branthwaite in strong contention.

Ben White made himself unavailable for England selection after the World Cup in Qatar in 2022 when he left the squad but Tuchel has spoken to the Arsenal defender who can play both at right back and centre back. While Chelsea captain Reece James is also known and liked by Tuchel.

Jude Bellingham and Declan Rice are two near certainties to play for England in midfield with the third place up for grabs if Tuchel plays with a three-man midfield.

Kobbie Mainoo took that role at Euro 2024 but is currently injured, whilst Carsley introduced Angel Gomes, Morgan Gibbs-White and Curtis Jones during his interim time in charge.

And Tuchel has been at Selhurst Park for their past two Premier League matches and Adam Wharton. The former Blackburn man was included in the Euro 2024 squad but did not play a minute, yet has impressed since coming back from injury and could be the 'number 6' that England are craving.

Record goalscorer Kane's England place was one of the biggest talking points of the summer. But any discussion of evolving away from the Bayern striker has disappeared with the appointment of his former boss Tuchel and Kane's 10 Champions League and 21 Bundesliga goals this season.

Unusually for this squad, form and fitness means England's usual array of attacking talent is partly reduced.

Cole Palmer, Phil Foden and Jack Grealish are all out of form, Bukayo Saka and Noni Madueke are injured. They are competing with Anthony Gordon, Ollie Watkins and Morgan Rogers who are all having good periods. Could Aston Villa's Marcus Rashford, on loan from Manchester United, get a surprise recall?

In terms of formation, Tuchel has used both the 4-2-3-1 formation and a variation of 3-4-2-1, which he implemented at Chelsea in an impressively short amount of time for Champions League glory.

His sides can be described as pragmatic with an extremely high level of detail put onto each player. Not afraid of a direct style, his Bayern side knocked Arsenal out of last season's Champions League maximising long diagonal balls into pacey wingers for one v one situations.

The biggest clue as to whether Tuchel will play three at the back will be if six centre-backs options are chosen to cover the two games, rather than four or five, including versatile players like White. Another hint would be the inclusion of Crystal Palace's Tyrick Mitchell, who is playing as left wing-back under Oliver Glasner.

Southgate was criticised for his failed Luke Shaw fitness gamble in the summer and left-back remains a dilemma for Tuchel.

In-form Newcastle defender Lewis Hall - who was given his Chelsea debut by Tuchel - was nailed on, before being ruled out for the rest of the campaign with an injury.

However, Arsenal's Myles Lewis-Skelly has had an impressive breakthrough season despite actually being a midfielder at youth level.

Palace defender Mitchell has not added to his two England caps since making his debut in 2022, but with Tuchel being a regular visitor to Selhurst Park, he may be an outside bet.

Then there is Tottenham's Djed Spence, a right-footed left wing-back nominated for February's Premier League Player of the Month after finally getting a run of games under Ange Postecoglou.
