Arsenal fullback Nacho Monreal says they must not be obsessed with Robin van Persie for Manchester United's visit this weekend.

While Monreal acknowledges the Dutchman's threat, he says the champions are full of dangerous players - not least on the flanks.

"Teams like Manchester United don't just have gifted wingers, they have a squad with a lot of depth," the Spanish international told Arsenal Player.

"Their players are of the highest level, you can't just focus on one player because their team is full of players who can create and score.

"We must be on our guard and be aware of certain key players, like Robin, who has scored a sack of goals this year and is playing well. He is one of their main threats."
