The second half is underway at Old Trafford as Manchester United trailed after just 13 minutes, with Riccardo Calafiori putting Arsenal 1-0 up in the big game of the Premier League's opening weekend.
United finished 15th last season, while Arsenal lost out on the Premier League title to Liverpool, but it's a new season and anything can happen.
The Gunners hand a debut to new striker Viktor Gyökeres, who made his name under Man United manager Ruben Amorim at Sporting CP, and United's new striker Benjamin Sesko came off the bench for his Premier League debut as Bryan Mbeumo and Matheus Cunha started.
