Alexis Sanchez believes an “abrupt” move from Arsenal to Manchester United has contributed to his slow start to life at Old Trafford.

Sanchez has scored a single goal since switching from Arsenal during the January transfer window, with Henrikh Mkhitaryan moving the other way.

Jose Mourinho has acknowledged it was not the ideal time to sign Sanchez, who had been linked with Manchester City and was set to become a free agent at the end of the season.

And Sanchez – an unused substitute for the FA Cup quarter-final win against Brighton and Hove Albion – accepts he has not performed as well as he would have liked since joining United from Arsenal.

“Seeing as I demand a lot of myself, I expected something better,” Sanchez said during international duty with Chile.

“After my arrival at United, it was hard to change everything very quickly. I even hesitated to come here [to Sweden with Chile].”
