Both sides head into the game after Premier League defeats, but Monk believes Arsenal's 6-0 humiliation against Chelsea, in Arsene Wenger's 1000th game in charge, makes them a dangerous opponent.

"We expect a reaction from them," Monk told reporters. "They're up there in the league and pushing for a different reason [to Swansea] and we expect a reaction from them.
"That's the message to my boys this morning and we'll try and go up there with the right attitude and put on the right performance to come away with something.
"But it's a very tough game, very tough team and we're in for a very, very hard night."
Despite their recent slump, Monk is confident his side can end their recent wobble and climb away from the drop zone.
"Their attitude is spot on," he added. "I'm confident with this bunch. They're confident that we can get out of this situation.
"It's not as if we're chasing trying to climb and chasing teams ahead of us in terms of points.
"It's in our own hands and we have to make sure and be very careful we don't make mistakes and cut them out of the games as quickly as possible."
