Southgate must have held his breath as key defender John Stones lay on the Wembley turf early on after an Iceland player fell on his ankle, a problem which eventually saw him replaced by Ezri Konsa at half-time.
With his long-time central defensive partner Harry Maguire ruled out of Euro 2024 with injury, the last thing Southgate and his vulnerable rearguard need is a problem for a player on who much will rest in Germany.
Stones actually could have done better for Iceland’s goal but there was an element of rust about his performance, and that of a number of Southgate’s stalwarts, that means they looked short of the sort of match sharpness they will need against Serbia.
He has only played 15 game and 1,073 minutes for Manchester City in 2024 and could have done with playing 90 untroubled minutes here to hone that fitness.
Instead, Southgate will be hoping the knock he took is not serious for a player who has had his share of injuries. Crystal Palace’s Marc Guehi looks a probable starter against Serbia. Southgate will pray Stones is alongside him.
Kieran Trippier also looked off the pace at left-back, a position which is still something of a headache for Southgate with Luke Shaw making progress having not have played since early February.
Trippier is 34 in September and has suffered with injuries and loss of form this season. He has played only 13 games and 931 minutes for his club this year – and it showed. If he is to start at left-back against Serbia, it will still be with question marks against his name.
