Gareth Southgate’s England squad for Euro 2024 has been a constant topic of debate ever since they crashed out of the 2022 World Cup in the quarter-finals to France.

That debate will soon be over, with the England boss naming his provisional squad for Germany on Tuesday, from 14:00 BST.

We take a look at some of the key issues before the announcement and ask you to pick your preferred starting XI for the Three Lions’ opening game against Serbia.

This area of the pitch is probably where England have the most depth.

At one point you could have predicted that Southgate’s front three would be Bukayo Saka, Harry Kane and Marcus Rashford.

However, with Rashford’s form and fitness with Manchester United being up and down, the left side of England’s attack is up for grabs.

Rashford was the player who brought electric pace to the England attack and, even when playing poorly, that ability to run in behind teams meant his place was safe.

However, Phil Foden has had the best season of his career – often played on the left – and it would be very hard for Southgate to leave him out.

Anthony Gordon has also had an excellent season for Newcastle and made his England debut in March. His work-rate and discipline is a big plus for him, as is his ability to run beyond the last defender.

Jack Grealish is another who missed the last international camp. He’s been in and out of the Manchester City side in another dominant campaign for them, but may have slipped down the pecking order for England. He’s been an important impact player for his country though, and played a big role in Euro 2020.

Cole Palmer must also be a consideration. He’s scored 22 Premier League goals this season and been Chelsea’s standout player. He also had a 100% penalty conversion rate and that could be another factor for Southgate as he plans for the knockout part of the tournament.

Two of the three central midfield positions are virtually guaranteed thanks to Declan Rice and Jude Bellingham. So the question for Southgate is who are the options for the third slot?

In England squads, Liverpool’s Trent Alexander-Arnold is considered a midfielder, but that experiment has been curtailed by injury.

Jordan Henderson’s move to Saudi Arabia, and then Ajax, leaves his position in the squad vulnerable and Kalvin Phillips was not picked after his disappointing loan move to West Ham.

Manchester United youngster Kobbie Mainoo only made his England debut in March, bypassing the under-21s, and was very impressive in friendlies against Brazil and Belgium, increasing the clamour for him to make the starting XI.

Harry Kane is obviously England’s first-choice striker but a back injury sharpens the focus on his understudies.

Ollie Watkins has had an incredible season for Aston Villa, scoring 19 non-penalty goals in the Premier League and providing 13 assists as they qualified for the Champions League.

He has played 11 times for England, starting four games and scoring three times.

Southgate has referenced that the team need to play to Watkins’ strengths and adapt to the fact that he is a different player to Kane.

Another back-up for Kane is Brentford’s Ivan Toney. He is more similar in style to Kane, as the focal point at the head of the attack. He scored his first England goal from the penalty spot in March and looked at home on the big stage.

However, Toney’s club form has not been great, not scoring in 12 games since hitting four goals in five on his return from a ban for breaching FA betting rules.

The left-back area has been one of the problematic positions for Southgate. Newcastle’s Kieran Trippier has played there in the biggest England games in recent times. He started the crucial match against Italy at Wembley to secure qualification for the tournament.

If every player was fit, Manchester United’s Luke Shaw would be the first-choice left-back, but he has suffered a setback in his recovery from his latest injury.

Ben Chilwell has also struggled with injuries, and the Chelsea player did not totally convince against Brazil and Belgium.

Manchester City’s Rico Lewis won man of the match in his first England start and was called up as an injury replacement in the last international break, while Liverpool’s Joe Gomez is another option following a recall afterfour years away last time out.

City’s Kyle Walker seems an obvious starter at right-back, while John Stones and Harry Maguire seem the favoured starters at centre-back, with the latter expected to have recovered from injury.

If Southgate is looking for extra defensive options, Bayern Munich’s Eric Dier boosted his chances after an impressive loan spell from Spurs. And of course there is the Ben White issue – the Arsenal defender has been a huge part of the Premier League’s meanest defence but remains unavailable for selection.

When speaking to the BBC, Southgate said that the squad sizes being increased from 23 to 26 players could allow him to take a risk on players who are not fully fit.

Southgate has usually been loyal to the core of his group but there are a couple of players who could have made a late break to be in his squad.

Crystal Palace won six of their last seven games of the season and Eberechi Eze and Adam Wharton starring.

Eze made his England debut last year but injury has held him back from adding to his two caps.

Wharton has progressed to the England U21 side and his passing ability has seen teams at the top end of the Premier League already taking notice of his talents.

Southgate values the pathway within the England setup and a number of former U21s can be expected to make his squad. The recent crop won the U21 European Championship last summer and Levi Colwill and Gordon have made senior debuts since then.

Liverpool’s midfielder Curtis Jones was one of the players of that tourname an would be an interesting option in an area England aren’t blessed with loads of options.

Chelsea captain Reece James looked to be the next England right-back in waiting, but has started just five Premier League games this season due to injury.

He has undoubted quality though and his freshness could be an asset if England go deep into the tournament.

Two other forwards worth a mention are Chelsea’s Raheem Sterling and Manchester United’s on-loan Jadon Sancho.

Sterling was once England’s major tournament talisman and Sancho’s Borussia Dortmund form has helped the German side reach a Champions League final. Both would be a surprise, but could sneak into a larger initial training squad.
