The Red Devils' shiny new strikeforce excited the Old Trafford faithful but they were let down by their hapless goalkeeper
Manchester United's expensive new front line looks like money well spent after Bryan Mbeumo and Matheus Cunha gave Arsenal a real fright but Altay Bayindir's blunder in the 1-0 defeat underlined the need for the club to invest in a new goalkeeper.
The Turkish goalkeeper's weak hand pushed a Declan Rice corner towards the far post and would have resulted in an own goal had Ricardo Calafiori not nudged it over the line with his head. The blunder undid a very positive start from United, as Mbeumo bullied Arsenal's defenders and flew forward with intent, even if his final shot was lacking.
United defended well throughout and Arsenal barely troubled Bayindir after scoring,, making the goalkeeper's error all the more frustrating. New £74m signing Benjamin Sesko made his debut in the second half but could not come to the rescue, missing the target with his only opportunity.
