Leeds United have been observing Dennis Cirkin's development at Sunderland as they assess possible transfer targets. The 22-year-old left-back has emerged as a key player for Sunderland since his departure from Tottenham Hotspur in August 2021. His notable performances in the Championship, where he has netted three goals and contributed two assists in 32 appearances this season, have attracted the interest of several clubs. With only a year remaining on his contract, Cirkin is anticipated to transfer if Sunderland does not achieve promotion. Leeds United, along with Tottenham, Chelsea, Crystal Palace, West Ham United, and Everton, are among the clubs keeping an eye on the England U-20 international. Leeds considers Cirkin a potential recruit to enhance their squad, particularly as they seek to fortify their defensive lineup.
