Carrick has done well, nobody can question that, the results are there. However, the problem would be expecting even more out of him. I am seeing United fans over at reddit requesting a title win finally , after many years without a title.
Now, I get that United won many titles and that is why wanting one more is normal for them but considering the shape of the team, if they are not even in top four, I would not be shocked. For a team that barely get out of relegation last year, to a team that is third place this year, I think the yare wanting too much, and should be happy with what they have. I do not get why Carrick should be considered bad, if he ends 6th for example, even that is good for a team like United.
Any Manchester United fan that expect Carrick to win a trophy next season is not ready to watch his club when they season start, the reason why i said that is because how many players did Manchester United sign in this transfer window? Manchester United only sign two players and one deal is off because Enderson from Atlanta failed his medical test and the deal was not completed, Manchester United at this point only sign one player and that is Santos from Chelsea which is not enough for the club to win a trophy.
I know that Carrick managed players last season but next season is going to be different because Manchester United is participating in every competition next season, they are playing every competition in the league and also Champions League which means that they will play two or three times in a week, Manchester United need to have a good squad so that they can rest some players in some games, Carrick can win a trophy if the players play the way they do last season but the club is also going to contribute to the squad.
