The 18 year old was given a work permit earlier this week ahead of his move to Old Trafford, and with his arrival likely to be completed by Sunday, Sir Alex has closed the Old Trafford door for the summer.
“Henriquez is on his way back to Manchester.
“He had to go back to Chile after he got the work permit on Tuesday. We’ve had an option [on him] since he was 14 when he played against our youth team.
“He came over when he was 15 and then 16. We kept in close contact with him in that respect and, when he got to 18, it was a matter of whether or not we left him for another year or brought him in. But he had such a good summer with Chile’s Under-20s, that we thought it wasn’t worth waiting. We may as well do it now.
“That took away a lot of interest from other clubs. We had the option on him, but options only last so long and we decided to take him in. He’s quick and a good finisher and he has a terrific physique for a boy of 18. He should be here on Sunday.”
“We definitely won’t be buying anyone else. There is no movement about anyone going the other way.”
