Sir Alex Ferguson has said that striker Angelo Henriquez will be Manchester United's last summer signing.

The 18-year-old Chilean follows forward Robin van Persie, midfielders Shinji Kagawa and Nick Powell plus left-back Alexander Buttner to Old Trafford.

Ferguson also said that the club are not closer to selling either, with Dimitar Berbatov linked with a move.

"We definitely won't be buying anyone," Ferguson said. "There is no movement about anyone going the other way."

Who is Angelo Henriquez? Born: 13 April, 1994 in Santiago, Chile Height: 1.81m Position: Forward Universidad de Chile league record in 2012/13: 11 appearances, eight goals International record: Represented Chile at youth levels from under-15 to under-23, but yet to make his senior debut

Club record buy Berbatov has drawn interest from several European clubs since the £24m arrival of Van Persie.

Henriquez will further increase Ferguson's options up front when he travels to England on Sunday after being granted a work permit and visa. And the Scot revealed he had monitored the progress of the Universidad de Chile youngster for several years.

"We have had an option [to sign him] since he was 14 when he played against our youth team," the 70-year-old said. "He came over when he was 15 and then 16.

"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. He's quick and a good finisher and he has a terrific physique for a boy of 18."

Ferguson also stated he expected 23-year-old Dutchman Buttner, signed from Vitesse Arnhem on Tuesday, to feature from the substitute's bench against Fulham on Saturday due to the number of injured defenders at the club.

He said: "Patrice Evra could actually play at centre-back, he has done in the past. But it [Buttner's arrival] gives us a stronger squad, that is the most important thing.

"We've been monitoring Alex for a while. He's a straightforward, attacking, quick full-back who will be a terrific addition to our squad.

"Patrice Evra has played an average of 48 games a season for the last five years, an incredible statistic. He's still a fit lad but he is in his 30s now and Alex gives us good back-up.

"He will provide Patrice with a good challenge."
