Swansea City manager Garry Monk has defended Manchester United following the recent criticism of their style of play.

Sam Allardyce labelled Louis van Gaal's side "long-ball United" after they played out a 1-1 draw with West Ham United earlier this month, but Monk believes that the Dutchman has ensured that his players are capable of changing tactics during games.

"I understand what was said but, in this game, you have to be adaptable," the Swansea boss told reporters ahead of the visit of United this Saturday. "You can't have one set way and Man United have done that well.

"They can change their style in games, which they did against West Ham, and it was only in the last five minutes when they used their strength well with [Marouane] Fellaini to get a point out of the game.

"It's a strength to be adaptable but they can produce fantastic football with world-class players all over the pitch."

Swansea are looking to record a Premier League double over United following their 2-1 victory on the opening day of the season.
