Transfer speculation continues to mount as Barry Bannan has been linked in recent days with a move to Preston. The midfielder, currently playing for Sheffield Wednesday, could add a new dimension to the squad if the rumoured interest turns into an official approach before the end of the transfer window. Preston remain optimistic, but the deal is not without hurdles. Stoke and Millwall continue to monitor developments and could yet re-enter the race if negotiations stall or valuation gaps remain unresolved. So far this season, Preston are steady at both ends (1.38 goals scored per game, 0.96 goals conceded per game). The role for Barry Bannan would be to keep that balance while lifting performances across the pitch. There are currently no rumoured links for either Sheffield Wednesday or Preston.
