Queens Park Rangers manager Mark Hughes is expecting a "big test" when his side hosts Arsenal in the Premier League on Saturday.
The struggling R's are currently 18th in the table following four defeats in their last six matches.
Meanwhile, the Gunners are the league's in-form side with seven consecutive wins.
"Arsenal are playing exceptionally well, obviously they're winning games and their confidence is growing as a consequence of that," said Hughes.
"I think the likes of [Tomas] Rosicky are playing exceptionally well at the moment so they have key players playing at the top of their ability.
"As always it is a big, big test for us going up against an Arsenal team who, in current form, are as good as it gets."
Rangers can move out of the relegation zone with a win against their London neighbours this weekend.
