Diego Maradona suggested that Argentina coach Jorge Sampaoli find a new country to call home if his charges continue to underachieve at the 2018 World Cup.
The 1986 World Cup winner stole the show in Moscow on Saturday as he took in his nation's first game of the finals.
His outrageous orange sunglasses, however, were just about the only bright spot of a disappointing draw against a determined Iceland team.
And the Albiceleste legend pulled no punches in registering his displeasure at what he saw from Sampaoli and his players.
"If he carries on like this, Sampaoli can't come back to Argentina," he fired in Telesur's 'De la mano del Diez' show.
"It is appalling not to have a single prepared move. Knowing that all the Icelandic players are 6'3" we looked for headers at all the corners. We didn't do a single short one."
"His game plan was a disgrace. I don't blame the players. I blame a lack of preparation because there obviously hasn't been any," Maradona added.
"The time for talk is over. You can take 25 coaches with you, but do some work - we saw that Iceland had worked harder than Argentina and that hurt me a lot."
