Add to a growing list
The Italian goalkeeper's new two-year deal, makes him the latest first-team player to put pen to paper on a new deal, following on from Patrick van Aanholt and Jermain Defoe.
It is now expected that the club will look to tie down but Kirchhoff and Allardyce, with both just having a year left on their current contracts.
Kirchhoff has become a firm favourite on Wearside, after his move from Bayern Munich only in January, and is expected to sign on without a hitch.
The club's main mission will be to secure the services of their manager, who was crucial in their Premier League survival last season.
It is reported by the Sunderland Echo, that the club have been looking to tie down Allardyce for several weeks.
The new deal amidst the growing rumours of Allardyce been the next England manager, making the new contract more vital, with Allardyce emerging as the top homegrown candidate, after the resignation of Roy Hodgson.
Committing their future
Mannone is the latest name to sign a new contract, which will keep him at the club until 2018.
The former Arsenal man managed to lose his place to Costel Pantilimon, after a excellent first season, but reemerged under Allardyce and was a big part in their survival, and he shared his delight at signing a new deal.
Mannone told safc.com "I've just got back and what a way to start the season" as "it's a massive boost for me and my family" as "I love the club, the fans and everyone involved."
Sunderland AFC will take on Hartlepool United at Victoria Park on Wednesday, July 20 with kick-off at 7:30pm BST.
