Not only Ten Haag, but all coaches should be given more time to improve the team's performance.
Manchester United should learn from their repetitive mistake after Sir Alex decided to retire as a coach.
They used to hope too much from a new coach but they did not give longer time for the coach to prove.
However, I still doubt that Ten Haag will be able to make United back to what they were in the golden era with the current squad.
They need some more fresh great players to replace the existing players who are not really give contribution in the last few seasons.
The main problem with United is not the coach, or the players but the club in general. The owners and united legends have been using their quotes to designate the club, Sir Alex Ferguson still have saying in the club, not just him but others have been dropping quotes and also have a right to point out players that he feels like is suitable for the club. I strongly believe that Erik Ten Hag will push United to his best capability, but their signings this summer, I don't value the players. United needs experience players which the young ones in the team will imitates and put up an impressive performance.
