The Chile star looks set to leave the Emirates in favour of linking up with Pep Guardiola at the Etihad, with his future to be decided after the international tournament.
On Sunday, he had the chance to put his country ahead, with the world watching on.
With midfielder Arturo Vidal striking from distance, it was Alexis who reacted quickest, darting into the six-yard box to collect the loose ball.
With Germany goalkeeper Marc-Andre ter Stegen sprawling, though, the Arsenal star fluffed his lines.
Then, just two minutes after the miss, Borussia Mönchengladbach's Lars Stindl put Germany ahead with a tap in.
How's your luck?
