Gareth Southgate joked he would select more right-backs in England's Euro 2020 squad if he could, after four players who fill the role were picked in his 26-man pool.
Kyle Walker, Kieran Trippier, Reece James and – despite several media reports to the contrary – Trent Alexander-Arnold were selected in England's squad for the tournament, which starts on June 11.
Liverpool defender Alexander-Arnold missed out on the March internationals and reports suggested he would be the biggest name to be cut from England's provisional squad.
Asked to explain his decision, Southgate told a news conference: "We went through this last week, yes we have four players who play sometimes at right-back for their clubs, Kieran, Reece have been playing wing-back or right of a three, Trent plays at right-back, Kyle Walker has played in the right of a three for us.
"Basically they're in our best 26 footballers and if I could have picked a fifth or a sixth right-back, I probably would have done!"
Alexander-Arnold has won acclaim for his attacking qualities, and Southgate last week said he felt the 22-year-old, who has 12 caps, could be versatile enough to play in midfield.
Pressed on that suggestion in Tuesday's media conference, Southgate said: "We're here to play nine games and we already have some injury doubts, I'm sure we're going to face other difficulties in the next four or five weeks.
"We need adaptability, good professionals, tactically savvy players – we're fortunate we've got old and young players who fit all of those categories."
There can be little doubt over his proficiency going forward, though there has been debate over Alexander-Arnold's defensive abilities.
In the Premier League, he made three errors leading to shots and one that led to a goal in the season just ended, whereas James and Walker made no such mistakes.
Trippier, who helped Atletico Madrid win LaLiga, made just one error that led to a shot. Alexander-Arnold's tackle success rate (58.9 per cent) was below that of each of his rivals for the England role (Walker 65.5 per cent; Trippier 63.9; James 63.6), and he was part of a Liverpool team that conceded a goal on average once every 76 minutes when he featured.
Trippier, a key part of Atleti's tight-knit defence, could point to the new Spanish champions conceding only once per 191 minutes when he was on the pitch.
In Alexander-Arnold's defence, he played far more minutes in league games than each of his rivals (3,033 - next most is Trippier with 2,477), and Liverpool's backline frailties were to a large extent affected by the injuries that kept Virgil van Dijk, Joe Gomez and Joel Matip out for much of the season.
Should Alexander-Arnold indeed be utilised as an alternative midfield option, it may go some way to support Southgate's reasoning for leaving out Jesse Lingard.
Out of favour at Manchester United, the midfielder enjoyed a brilliant loan spell at West Ham, scoring nine goals in 16 league appearances as David Moyes' team secured European football for next season.
"Jesse's done incredibly well to get back in the race. Back in January he was a million miles away from being selected for an England squad," Southgate said.
"He had a good spell with West Ham, he's been a player who's played so well for us with England, we've got total trust in the way he plays, he's reliable, a great member of the group.
"He will play tomorrow [in the friendly against Austria] because we've got [Jadon] Sancho ill and we've got a lot of players not available and for the balance of the team he'll start, so he deserves that opportunity to go and show me that I'm wrong, straight away!"
