Haalaand and Nunez both departed from competitions outside England and they certainly still need time to adapt to the English league game, indeed in the Community Shield title match against manchester city yesterday Nunez performed quite well and he indeed to be praised, unlike the case with Haaland who was judged to be lacking contributed to manchester city in that match, but in some pre-season games with liverpool actually Nunez also performed poorly but gradually he was able to restore his game performance, that is also what happened to Haalaand at this time and maybe he still needs time in manchester city, in my opinion quality the two strikers are equally good and it is possible for them will become rivals in terms of the top scorer in the English league next season.
Well I would say great if his first season in the Premier League was able to score 20 more goals. I won't argue if you call him great just because he beat Manchester City, but he contributed well to his team by contributing one goal.
I expect competition between Haaland, Nunez and also Ronaldo if he wants to stay at Manchester United. These three players will be compared until the end of the season, but we don't know what they are capable of achieving. Hoping for the best, that's for sure.
