Furthermore, Di Maria was played out of position for much of his time at Manchester United. Van Gaal often deployed him as a winger, despite the fact that he was most effective when playing in a more central role. This meant that Di Maria was unable to make the most of his abilities, and he struggled to have the same impact that he had at Real Madrid.

Another factor that contributed to Di Maria's failure at Manchester United was the pressure that came with his record transfer fee. The Argentine was seen as a marquee signing for the club, and he was expected to deliver immediately. However, he was unable to live up to these expectations, and this put added pressure on him to perform.

Finally, Di Maria's time at Manchester United was also impacted by the arrival of other players at the club. The signing of Dutch winger Memphis Depay, in particular, meant that Di Maria was no longer seen as the main attacking threat for the club. This, combined with his own poor form, meant that he struggled to make an impact in his second season at the club.

In conclusion, the signing of Angel Di Maria proved to be a mistake for Manchester United. The Argentine winger failed to adapt to the physicality of the Premier League, had a poor attitude on and off the pitch, was played out of position, and struggled with the pressure that came with his record transfer fee. Ultimately, he was unable to deliver the performances that were expected of him and left the club just one year after arriving.
