The report says no attempts were made to vandalise either property, and there is no indication that either player faced a confirmed attack. Still, the reported security presence underlines how quickly football symbolism can become personal.
During the celebrations, Martínez reportedly held a banner reading: “The Falklands are Argentina's.” Mac Allister was nearby as the message was displayed, while other Argentina players also took part. The Falklands/Malvinas dispute remains politically and emotionally sensitive in both countries, making the celebration more provocative than a routine victory chant.
The reaction also challenges the idea that English club supporters automatically follow England with the same intensity.
Martínez represents Argentina internationally but is a central figure for Manchester United supporters. Mac Allister plays for Argentina while carrying strong affection from Liverpool fans, where local identity has often been treated as distinct from national allegiance.
That separation is not unique to Manchester or Liverpool. Club football dominates the weekly emotional calendar, and players can become symbols of their club communities even when representing a country viewed as a rival.
Provocative banners are part of football’s theatre, but the reported move to protect private homes marks a serious boundary. Security does not prove that wrongdoing was imminent, particularly when the same report says no vandalism occurred. It does show why clubs and players must separate legitimate rivalry from intimidation.
The next Argentina-England meeting will test whether the issue fades with time or returns through another flashpoint. For Martínez and Mac Allister, the immediate challenge is to return to club football without allowing a national-team celebration to define their relationship with supporters.
