Andres Iniesta has said that Champions League with Arsenal will be tough. Andres Iniesta Catalans travel to Emirates Stadium for the first leg of their last-16 tie as strong favourites but the World Cup final goalscorer refuses to count his chickens before they hatch.

Barca ran out 6-3 aggregate victors in last season's quarter-final showdown with the Gunners but Iniesta is adamant things will be vastly different this time around.

"We are not a machine," he insisted. "It won't be easy. This isn't a walk along the promenade for us.

"But Barcelona never take the field looking to be arrogant. That would be an enormous error.

"People speak about the matches last year but things are completely different.

"No two games are ever the same and we are aware Arsenal will be very motivated this time. That makes them even more dangerous.
