Multiple sources are reporting an imminent transfer move for Diogo Leite, with Lazio reportedly showing interest in the defender currently plying his trade at Union Berlin. With both teams looking to strengthen their squads, the move could have a massive impact on their seasons going forward. Lazio remain optimistic, but the deal is not without hurdles. Fiorentina continue to monitor developments and could yet re-enter the race if negotiations stall or valuation gaps remain unresolved. Lazio's back line has been a real strength this season, conceding just 0.86 goals per game (19 in 22). Diogo Leite would be expected to slot into that unit and hold his own in an already solid setup. Reports suggest Lazio are monitoring Davide Frattesi, Daniel Maldini and Tim Iroegbunam whereas Union Berlin have not been associated with other players at this stage.
