Card-happy referee Mateu Lahoz will not be making friends with the Argentina and Netherlands camps anytime soon, especially with two of his 17 bookings going to Albiceleste full-backs Gonzalo Montiel and Marcos Acuna, who are now suspended for the semi-final.
Montiel was unlikely to challenge Molina for the right-back berth, and Acuna will pass left-back responsibilities over to Nicolas Tagliafico as he takes his place on the naughty step, but Scaloni thankfully witnessed no players pick up injuries in the 120-minute quarter-final.
Alejandro Gomez is pushing to be available as he steps up his recovery from an ankle sprain, while Rodrigo De Paul and Angel Di Maria - who have both been nursing problems of their own - will expect to be fit to start the semi-final.
Scaloni opted to match the Netherlands' setup with a five-man backline - bringing Lisandro Martinez back in from the cold - but a switch to a four-man defence could see the Manchester United man now cede his place to the fit-again Di Maria.
As for Croatia, Dalic was blessed with a fully-fit squad for the quarter-final win over Brazil and should be working with all of his troops for Tuesday after Borna Sosa and Mislav Orsic both recovered from respective illnesses.
Amid his side's well-documented struggles for goals, Dalic brought Mario Pasalic in from the first whistle against Brazil, and the Atalanta BC man can feel confident of holding his position on the right wing.
Andrej Kramaric may be fearing for his place at the tip of the attack after Petkovic's dramatic equaliser in the quarter-finals, but the Hoffenheim man has started every game in Qatar so far and will likely hold his place from the off.
Argentina possible starting lineup:
E. Martinez; Molina, Romero, Otamendi, Tagliafico; Fernandez, De Paul, Mac Allister; Di Maria, Messi, Alvarez
Croatia possible starting lineup:
Livakovic; Juranovic, Gvardiol, Lovren, Sosa; Modric, Brozovic, Kovacic; Pasalic, Kramaric, Perisic
