Lackluster growth in the euro area is just as miserable as that seen in the U.S., the former president of the European Central Bank (ECB), told CNBC on Friday, defending the central bank's policies.

"I would like to underline something that is not something well-perceived. I compared over the last 12 months real growth in the U.S. and real growth in the euro area and, to my great surprise, the euro area had growth of 1.6 percent over 12 months whereas in the U.S. it was 1.2 percent," Jean-Claude Trichet told CNBC on the sidelines of the Ambrosetti forum.
