On Thursday, Lionel Messi gave the Monumental crowd and Argentina as a whole a send-off to remember as he lit up Núñez. On Tuesday, the Albiceleste were reminded exactly what they will be missing when the little genius finally decides to call it a day. Lautaro Martínez came off the bench to add Argentina's second before Messi rounded off the rout by converting a sublime collective move that showed off Lionel Scaloni's team at its finest and most fluid. That is the good out of the way; now, I'm afraid, we have to cover the bad. Miss him when he's gone?
