"I respect very much how David Moyes has made his team, not having the highest budget, and managing a team like that shows he is a very good professional," said Hiddink.
"It is a tough team. They have shown it twice against Chelsea with two draws. They have very good tactical discipline and on top of that they have quality players who can make a difference.
"They have very skilful and smart players and are a difficult team to play against."
