Tottenham Hotspur are exploring a move for the Sunderland defender Dennis Cirkin when the transfer window reopens in January, as per TBR. They are looking to add to the homegrown quota at the club, and bringing the 23-year-old back to the club would be ideal for them. Cirkin came through the ranks at Tottenham, and he has done quite well for Sunderland. Tottenham have tried to sign Cirkin in the past as well.
