So why didn’t he want to take one tonight? Very, very odd.” A third wrote: “Not liking the fact Sesko was the last outfield player to take a pen either, doesn’t fill me with much hope.”A fourth said: “Sesko really doesn’t want to take a penalty. Not a great sign in your striker.”Another added: “Has £74m Sesko seriously bottled taking a penalty against League 2 Grimsby here.”Sesko had taken 11 penalties before the defeat in domestic and international football and scored all of them.Manager Ruben Amorim admitted after the game that the penalties did not matter as the humiliation had already happened.He told MUTV: “In the end, the penalties don’t matter.“After the game, the penalties if you win or you lose, the feeling [about the 90 minutes] should be the same.‘Let’s focus on the next game and then we have time to think about things.“We have a lot of debts with our fans so let’s focus on the game.“We have a job to do, a job to prepare and then we’ll stop and think things through.”Amorim was labelled as a “coward” by United supporters after he appeared not to watch the shootout.Supporters demanded that he be sacked from the Old Trafford dugout after he was seen fiddling with a tactics board on the touchline.
