The same can be said to people going on about agents. When Raiola bought Zlatan and Pogba to the club, everybody was on cloud 9. However, after things didn't go exactly to plan and Raiola made noises about Pogba wanting to leave, suddenly he is a fat cnut and 'Man Utd should never buy a player represented by him again'. I have been guilty of the same things you said, but then we are 'fanatics' of Manchester United. Our love for the club is unconditional. And when the majority don't like the direction the club is headed, people at the top are on the chopping block.
That said, our season ended in May, and every Tom, Dick and Harry knew that we needed reinforcements in midfield and defence. I don't know why Woodward has not gone out and bought if not Maguire, atleast players like Upamecano or a Skiniar. Why not buy Bruno? Seems to me like Sporting is practically laying out the red carpet to sign him. I feel like haggling over 10 million pounds in the case of Bruno is useless when we have reports coming out that the turnover was close to 700 million euros. Not like Glazers are spending billions of their own money like the Sheikhs. Why not atleast spend the money that the club earns? A winger who has scored only 4 goals in his career and a 21 year old RB (as highly rated as he is) is not going to cut it next season, chief.
