Sunderland defender Dennis Cirkin has announced via his Instagram page that he will be leaving the club this summer. Cirkin signed when the club was in League One and helped them not only reach the Premier League but also qualify for the Europa League next season. His contract runs out this summer, and it appears that he will be set for a new chapter in his career. Cirkin played 126 games for the Black Cats, scoring eight goals, but found his game time reduced due to the signing and form of Reinildo last summer. However, he was still a valuable member of the squad and was regularly in match-day squads. Along with a number of other players, fans, and the club, will be grateful to Cirkin for helping the club rise from the darkest of times to where they are today. Cirkin's decision to leave the club has been met with sadness from the Sunderland faithful, who will miss his contributions on the pitch. The club will now look to rebuild and find a replacement for the departing defender. Cirkin's Instagram post was a heartfelt goodbye to the club and its fans, thanking them for taking a chance on him and making him feel at home from the very first day. He will always be remembered as a key player in Sunderland's rise to the Premier League.
