In January, the 29-year-old put pen to paper on a deal worth around £500,000-a-week with the Europa League champions. It means Sanchez is the fourth-highest paid player on the planet, behind Lionel Messi, Neymar and Cristiano Ronaldo.
Although there has not been any direct confrontations between the stars, Jose Mourinho is aware that a situation could explode at any time.
Sanchez, on the other hand, is enjoying his arrival at United.
The report suggests that the ex-Udinese striker is delighted with his treatment at the club and has felt very welcome.
