Mac Allister and Romero have won several international titles together, including the World Cup and two Copa Americas. This close relationship gives them a deep understanding of each other's strengths and weaknesses, both on and off the field.

Mac Allister recently shared his thoughts on Romero in an interview with the Argentine media, stating that he would love to see Romero join Liverpool. He praises Romero's playing style, saying that he makes the game look easy and gives him confidence.

However, with Tottenham's recent Europa League win, Romero is likely to remain with the North London club. Atlético Madrid has also been linked to Romero, making a move to Liverpool less likely in the near future.
