Manchester United Dutch scout Ed van Stijn is surprised by their deal for Vitesse Arnhem fullback Alexander Buttner.

Buttner has begun training with United for the first time today.

Van Stijn told Algemeen Dagblad: "Every season the club calls all their European scouts for a list of players.

"They ask you for a top five of the best players from the Eredivisie in any position. On the list, at the end of last season, I had Buttner at number three or four.

"I would place him behind Jetro Willems (PSV)."
