Ruben Amorim suffered his first defeat as Manchester United manager against Arsenal on this wednesday, 2-0. After the loss, which came on the 14th matchday of the Premier League, the Red Devils' coach pointed to set-pieces as a determining factor in the game's outcome. The Gunners' goals came from exactly two set-pieces. Amorim was unhappy with the result, but emphasised that it takes time for changes to be made.
