Rio was out in Chicago with the team for pre-season. Obviously I go into the training ground quite a lot with my children.“It does put us in an uncomfortable position but we have to be honest with what we’re seeing. Frankly it’s just not good enough.”Despite potential awkwardness, Rooney did not hold back on United’s struggles under Amorim.The ex-England captain added: “What’s important when you’re trying to implement a new style is to win games as well while you’re doing that.BEST ONLINE CASINOS – TOP SITES IN THE UK“Unfortunately for Man Utd, and for the manager, it’s been not too far off a year now and I think it’s less than one point a game.“Which in quite a lot of Premier League seasons is relegation form, which over nearly a year period is hard, it’s very difficult. It’s tough to watch, and to see.” Rooney then pinpointed the “powerful” factor that could prove to be pivotal if Amorim’s tenure is to fully unravel.United’s all-time leading goalscorer added: “There was an image, towards the end of the game, where I was seeing the Man Utd fans leaving. I’ve never seen that. Well, in my time, I’ve never seen Man Utd fans leaving.“And you could hear the fans singing Amorim’s name, but I think that is so powerful that the Man Utd fans were leaving the game because they knew the game was over and I think they were very disappointed in what they’ve seen.“It’s hard to see how it continues.”‘I AM NOT GOING TO CHANGE’Despite coming under intense criticism, Amorim vowed not to compromise on his system.The Portuguese boss, whose side are 14th in the Premier League table, said: “I am not going to change. When I want to change my philosophy, I will change. If not, you have to change the man.“We talk about this every game that we lose. I believe in my way and I am going to play my way until I want to change.“I see that we are doing better but the results don’t show that. I remember last year I played with my former club against City – we won 4-1.“It was not near the same amount of opportunities – the way we controlled that game compared to today.“In certain moments we were not better than City – I understand that. It is hard and the record says everything. I understand.”GettyRuben Amorim has won just eight of his 31 Prem games in charges of United[/caption]
