Xavi says Barcelona are wary of Arsenal's young gun Jack Wilshere ahead of tonight's Champions League showdown. Gunners skipper Cesc Fabregas is expected to return from a hamstring injury against his boyhood club, but Iniesta thinks that Wilshere, 19, poses an equal threat.
"We have analysed Arsenal and Cesc is not exclusively the key man," said Iniesta.
"Wilshere is also very important for Arsenal. He is still young, but could go far and be the chief in the team."
