Manchester United were a bit lucky, the whole game was possessed by Arsenal, if Arsenal attack was as strong as Liverpool then the number of goals in that match would be more numbered than yesterday score line. Arsenal had no progressive attack, they focused on one part of the field which United was aware and capable of defending themselves, a more better performance from Arsenal would have given them the winner but they were unlucky to share points when they needed it the most.
Ruben Amorim is a tactical coach that knows exactly what he's doing to equip the club. It might seems like he's wasting away precious time but at the end, everyone will be happy to have such an amazing coach, a manager that will bring out the balance proportion of the Red Devils. Manchester United don't always dominate the game when they faced their elite oppositions but if they clash with average teams, they will dominate every aspect on the pitch and ensure they suppress their oppositions until a goal is conceded. I can't say the same story when they're in meet with Arsenal. The Red Devils should buckled up because winnings comes from winning from home.
