Andrés Iniesta worried about Arsenal forward

Andrés Iniesta spoke toArsenal'swebsite about the first leg of the UEFA Champions League Round of16 match between the Gunners andthe Blaugranes on Tuesday evening. The skipper will see his former teammate, now Arsenal starAlexis Sánchez, for the first time since the Chilean left the Catalans to join the London side.And Iniesta is aware of Alexis' qualities after playing alongside him for so long. According to the Spanish midfielder, the winger is anunpredictable player that will make a dangerous Arsenal side even better, and capable to cause the defending champions a hard time."What makes Alexis so dangerous is that he is unpredictable.When hedribbles, when he attacks, he is a very strong player."He’s got skill and whenhe has the ball he always creates doubts. In that sense, we have to try to make him feel uncomfortable on the field and try to minimise his strengths.""Arsenal are known for having a style of play, a way of understanding football through having the ball. I also think thatthe type of players that their coach or that Arsenal look for are very similar."I think their strong spots are their quality, their talent and the way they play. The way they attack, the way they combine. I think they’re a very dangerous opponent in that sense."
