Speculation in Italy suggests the Newcastle goalkeeper is one of a number of names Milan are considering as a second choice stopper.
Several players could be in line to leave Newcastle United this summer after the club's relegation and one of those could be Tim Krul if Calciomercato are to be believed, with the Italian outlet claiming that AC Milan are interested in signing the Dutch goalkeeper.
Krul has been at St. James' Park for 11 years and became the club's first-choice stopper midway through the 2010-11 season, but has been hampered by injuries on occasion in his career.
The Netherlands international has racked up 185 appearances for the club, but has not featured since suffering a season-ending injury in early October.
Despite his fitness issues, Calciomercato report that he is one of a number of options being considered by Milan as they look for a new experienced back-up goalkeeper to bring in alongside teenage sensation Gianluigi Donnarumma.
Krul would likely be a fairly inexpensive option for the Italian giants, and whereas Newcastle would have been unlikely to sanction a sale 12 months ago, the situation has change dramatically since that point.
In the 28-year-old's injury absence, two potential contenders for the number one spot in the Championship have emerged in the form of impressive pair Rob Elliot, who was named the club's player of the season, and Karl Darlow.
Any potential deal would depend on Rafael Benitez, however, with the manager claiming after committing his future to the club earlier this week that he will not be pushed into selling any player that he wants to keep.
With Elliot and Darlow two promising options next season, though, the Spanish boss could well be persuaded to let Krul go if any serious interest comes in from the San Siro.
