Bayindir's gaffe highlights Amorim muddle and hands points to Arsenal

Blazing sunshine and a new marquee serving craft ale behind the Stretford End: Manchester United began in a shiny new world and finished in the gloom of another defeat.

First look at Altay Bayindir's howler that handed Riccardo Calafiori an easy header. But then zoom out and you see this: a crisis at No 1 for United that features Ruben Amorim going all summer not fancying André Onana and still turning up for the season opener without a high-end replacement. Result: Bayindir's ricket.

The head coach defended preferring Bayindir to Tom Heaton when reminded how the Turk allowed a similar goal - straight in from a Son Heung-min corner - last season in the 4-3 Carabao Cup defeat at Spurs. He denied, too, dropping Onana as he had not "trained" enough after injury and stated contentment with his trio of keepers. The 40-year-old has to say this yet Onana and Bayindir have a record of goal-costing errors.

Arsenal failed to fire throughout - Viktor Gyökeres's 60-minute debut was a non-event - but they did not need to with United so dismal at both ends.

Towards the close Bryan Mbeumo and Amad Diallo tripped over Arsenal players in a hectic scramble to cancel out Calafiori's strike: a snapshot of United's chronic toothlessness. Moments later, a better Mbeumo headed effort drew a good save from David Raya. There were further goalmouth scrambles but no United player could stick the ball in the net.
