A report from Spain on Tuesday suggested that the experienced defender has held talks with the San Siro side over a summer move, but Puyol has stressed there is no truth in suggestions that he could be on his way out of Camp Nou.
"All the information that has come out is false," Puyol stated via his official Twitter account. "I am solely focused on recovering from my injury and to be in top form at the start of next season."
Puyol has not featured for Barcelona since its 4-0 Champions League win over Milan on March 12 due to a knee injury.
The 35-year-old, who has made over 500 official appearances for Barcelona, has a contract with the Catalans until June 2016.
