Man United signs Dutch defender Alexander Buttner

Manchester United bolstered its defensive options Tuesday by

signing Alexander Buttner, while Chilean striker Angelo Henriquez

was granted a work permit to join the Premier League club.

The 23-year-old Buttner signed a five-year deal to leave Dutch

club Vitesse Arnhem, a day after United opened the Premier League

season with a 1-0 loss at Everton.

”Alexander is one of the best young left backs in Europe and

we’re delighted to sign him,” United manager Alex Ferguson said.

”He’s someone we’ve been watching for a while now. He gives us

some really exciting options in that position.”

In the striking department, United expects the 18-year-old

Henriquez to complete his move to England after being granted a

work permit.

”He will play his final game for Universidad de Chile tomorrow

and a further announcement on him joining United will be made in

due course,” United said in a statement.
