England's Nations League Finals preparations will be a voyage into the unknown for Gareth Southgate, with a swathe of players absent for the build-up and captain Harry Kane battling to be fit.
Having captivated the nation with last summer's run to the World Cup semi-finals, the Three Lions will have another shot at silverware in next month's inaugural finals in Portugal.
But the groundwork for the Nations League semi-final against Holland on June 6 could scarcely be much different to last year's thanks to UEFA's bewildering scheduling.
Southgate will be without 10 players until the eve of the tournament as Chelsea face Arsenal in the Europa League showpiece before the Champions League final between Tottenham and Liverpool on June 1.
With Manchester City's FA Cup finalists and Borussia Dortmund winger Jadon Sancho getting extra time off, Southgate will have just 12 of his 27-strong preliminary selection available when the squad meets up at St George's Park on Tuesday.
"It has been an incredible couple of weeks for English football," Southgate said.
"Both the European ties and the Championship play-offs, so really exciting matches and the start of trophies being handed out.
"We're looking forward to the opportunity to finish that summer off once everything is done – a great opportunity for us to build on the last 12 months.
"In terms of the squad, a bit larger than normal for obvious reasons.
"We have a lot of unknowns. Callum Hudson-Odoi and Ruben Loftus-Cheek would definitely have been in this squad, so very unfortunate for both of them that they look like they've both sustained injuries that may keep them out for some period of time, although we are waiting on full confirmation on Ruben."
Chelsea midfielder Loftus-Cheek suffered what appeared to be a serious Achilles injury in a post-season friendly in the United States on Wednesday evening, leading Southgate to select 27 players rather than 28.
The expanded squad offers padding should there be withdrawals ahead of the finals, while a big question mark hangs over Tottenham striker Kane five weeks on from ankle ligament damage.
"That is one of the unknowns, really," Southgate said.
"He's obviously working towards being fit for them for their final, and we have to see how that progresses, really. Clearly he's a player we'd want to give every opportunity to.
"His goalscoring record for us is phenomenally high and he's captain of the team, so we're keeping that door open and will see how things progress."
Southgate will "assess everybody post-Champions League final" due to the physical and emotional toll of the match, but Kane could yet go to the Nations League if he does not play in Madrid.
