Lisandro Martinez helped Manchester United secure a 2-0 victory over Manchester City at Old Trafford, marking United’s third Premier League clean sheet this season. The Argentine defender limited Erling Haaland before the Norwegian was withdrawn in the 80th minute, giving interim coach Michael Carrick a dream debut.

Before the derby, former Red Devils Nicky Butt and Paul Scholes mocked Martinez, suggesting Haaland would treat him like a toddler or toss him into the net. Martinez replied that criticism on television matters less than face‑to‑face exchanges, insisting he focuses on performance and will give everything for United.

United entered the match after a turbulent spell that saw Ruben Amorim dismissed and academy boss Darren Fletcher briefly in charge. The win trims a campaign that has yielded only one point in seven league games and restores belief, but the club still faces a shortened 40‑match season, leaving Carrick’s next steps under scrutiny.
