Manchester United are still dealing with a player who, according to rumors, will be signed because they are interested in buying Aubameyang and that too is competing with Chelsea who has now made a price offer.
Manchester United are very bad with transfer recent years and this summer too. They did not have good plan for execution and change from player A to player B when they are in panic. Yesterday, I read news that they just sent a transfer offer to Atletico Madrid for Joao Felix and got a rejection.
However, Liverpool position here can make Manchester United unable to move freely. Without Nunez, it is not a barrier because Klopp will certainly make the front line that Salah has been waiting for as his main center again.
Liverpool can beat Manchester United without Nunez because if we compare two clubs, Manchester United are in troubles, not Liverpool. Liverpool did not win in first two matches so they have their issues too but not too bad like United.
Nunez should learn more and the reaction of Klopp after the red card will help Nunez to calm down. Learn and practice to control himself better against provocative behavior of opponent defenders.
