Dutch international Cillessen was said to be among the 12 first-team players at the club who were told they would be allowed to move clubs this summer amid a huge squad clearout at Los Che, where Dani Parejo, Francis Coquelin, Rodrigo Moreno and Ferran Torres having already departed.
Reina, who will celebrate his 38th birthday this month, began his career at Barcelona before moving to Villarreal, but his most memorable stint was across a nine-year spell at Liverpool between 2005 and 2014.
He has since played for Bayern Munich and Napoli before his move to the Milanese giants in the summer of 2018.
The 37-year-old custodian has won a number of cup medals across his time with Liverpool and Napoli but played just five Serie A games for Milan before his January loan switch to the Premier League.
