When available, Martinez gives United a left-footed defender who can step into midfield, defend aggressively and improve the first phase of possession. His absence has often changed the balance of the back four, particularly when United have struggled to build attacks from deep.
The concern is continuity. The report says Martinez made only 18 Premier League appearances last season, with injuries and suspension limiting his involvement. That record makes it harder for the club to plan around him, even when his performances justify a central role.
A supporters’ poll cited in the report captured the dilemma rather than settling it. Of 5,024 respondents, 58% said United should not keep a player who is injured so often. Yet 37% backed retaining Martinez despite his unreliable availability, while 5% remained undecided.
That divide reflects two competing calculations. One prioritises squad certainty and asks whether United can carry a defender who repeatedly misses extended periods. The other values his influence when fit and argues that replacing his profile could be more difficult than managing the risk.
The club has not put a timescale on the latest absence, and Martinez is reportedly on a post-World Cup break while further medical information is awaited. That uncertainty should shape any decision more than the emotion of the latest setback.
United may ultimately need both answers: keep Martinez if his recovery outlook is encouraging, but strengthen the centre-back group so his absence does not destabilise the season. The next medical update, and the club’s approach in the next transfer window, will determine whether this remains a manageable risk or becomes a reason to move on.
