Dominic Calvert-Lewin, whose contract with Everton has expired, is attracting interest from Sunderland. The Shields Gazette reports that Sunderland are currently in pole position to land the free agent. However, they face competition from Celtic, as the English international is also drawing attention from the Scottish club, who are in need of a striker after cooling their interest in other targets. Calvert-Lewin, now a free agent, offers a valuable opportunity for both clubs, with Sunderland looking to strengthen their squad.
