The Gunners became the first Premier League team to score four goals in the opening half-hour of an FA Cup tie, as they overcame the frustration of seeing full-back Riccardo Calafiori pull up injured in the warm-up.

Eberechi Eze cast aside criticism of his performances by assisting the first two goals, teeing up Noni Madueke for a side-footed finish then offloading for Gabriel Martinelli to pick out the bottom corner from the left side of the area.

There was a huge hint of fortune about Arsenal's third goal as Bukayo Saka – a late replacement for Calafiori in the lineup – provided a dangerous centre that Jack Hunt turned past his own goalkeeper.

It was 4-0 soon afterwards as Christian Norgaard slipped Gabriel Jesus in behind, and the Brazilian confidently lifted his finish over Sam Tickle.

Kepa Arrizabalaga made a good save to deny Joe Taylor and preserve Arsenal's clean sheet, then Viktor Gyokeres smashed an effort against the foot of the near post, having replaced Saka at half-time.

Eze lashed into the side netting and Martinelli saw a header brilliantly kept out by Tickle as Wigan, who are still seeking a new manager after sacking Ryan Lowe last week, avoided suffering any further damage.
