Jack Grealish also made a return to Everton, though the nature of the deal wasn't specified. Sunderland secured the loan signing of Chelsea’s Leo Fofana. These moves represent a flurry of activity as clubs finalized their squads for the remainder of the season, seeking to strengthen areas of weakness or offload fringe players.
