Swansea manager Garry Monk has praised "adaptable" Louis van Gaal ahead of Manchester United's visit to the Liberty Stadium.
Van Gaal's tactics have often been criticised during his Old Trafford tenure and his team were dubbed "long-ball United" by West Ham manager Sam Allardyce after the recent 1-1 draw between the two sides at Upton Park. "I watched that game and I think the long balls I saw were in the last five minutes, which quite rightly they used to their strength with Fellaini in a forward position," Monk said.
"There's no problem with that whatsoever. It actually shows good strength that they can be adaptable.
"I understand what was said but in this game nowadays you have to be adaptable.
"You can't just have one set way of playing and I think Manchester United have done that well this season.
"They can adapt their style for any given moment or period of the game and that was the case against West Ham.
"Let's not forget they've only lost one of their last 15 league games so they're very effective whatever way they play," Monk said. "It takes time as a manager to implement ideas."
