Alexis Sanchez has admitted he expected “something better” after joining Manchester United.
The striker swapped Arsenal for Old Trafford in January, but has flopped in his first few games for his new club.
He has scored just one goal in 10 games since he joined the Red Devils, with Henrikh Mkhitaryan heading the other way.
His poor form was brought to the fore last weekend when Sanchez was dropped to the bench for United’s FA Cup win against Brighton.
Speaking from his Chile team’s base in Sweden, the 29-year-old said: “As I am self-demanding, I expected something better.
“After my arrival at United, it was hard to change everything very quickly. I even hesitated to come here [to Sweden, with the national team].
“I had asked permission to miss these games, but then I thought better and spoke with Claudio [Bravo] and told him that we should all be united.
“The change of club was something that was very abrupt – it was the first time I’ve changed clubs in January – but many things have happened in my life that are difficult.”
