Barcelona midfielder Yaya Toure admits Arsenal and Manchester United are the big threats for the Champions League this season.

"Right now Arsenal is playing great football in the Premiership and if they continue to play this way they will be a big threat to my team in the Champions League," he told skysports.com.

"I am also sure that an English team will be in the final.

"My brother is better than me now because he is playing at that level for the past six years. He is the big star, not me, even if my team is more recognised in the world because of its history."

Toure also spoke of his admiration for Arsenal's Premier League rivals Manchester United: "I can also see Man United having a big say in the Champions League.

"Their front five of Giggs, Scholes, Rooney, Tevez and Ronaldo is frightening."
