In June 2015, Dynamo Moscow were excluded from 2015–16 Europa League contention for violating Financial Fair Play break-even requirements. Samba reacted angrily with the respond in a Russian interview. Consequently, most of the foreign players left the club. In August, Samba went to Turkey to arrange a transfer to Trabzonspor, but the transfer fell through, with Trabzonspor manager Shota Arveladze commenting: "This is not the Samba I know, this is some kind of Mike Tyson. I need a football player, not a heavyweight boxer." He rejected a new contract from Dynamo Moscow, which began negotiation last April. Samba didn't play any games for Dynamo in the first half of the 2015–16 season, with his spot in the line–up taken by a new signing Vitali Dyakov. Dynamo manager Andrey Kobelev explained that Samba is suffering from a herniated disc in his neck and he required a surgery to correct it. After the surgery, his recovery took most of the rest of the 2015–16 season. He previously suffered a foot injury during a friendly match against AFC Ajax. He returned to action for Dynamo in a game against PFC CSKA Moscow on 24 April 2016. Samba later made three starts for the side, adding his 2015–16 appearance to four. However, his return was short–lived when he suffered another injury and was sidelined for the rest of the 2015–16 season.
