Multiple sources are reporting that Diogo Leite is the subject of an offer from Al-Ittifaq, who have made a move to sign one of their top transfer targets. The defender, currently at Union Berlin, is now at the centre of negotiations between the two clubs - while it remains to be seen whether the opening offer will be enough for the team to part with their man. Until a fee and conditions are finalised, the deal remains vulnerable to disruption - especially if Porto, Al-Riyadh and Vasco da Gama decide to make a formal offer of their own in the coming days. So far in this season, Al-Ittifaq are conceding 2.0 goals a game (8 in 4), more than they'd like compared to the Saudi Professional League standard. The hope is Diogo Leite adds a bit of steel and helps make them tougher to break down. Union Berlin have recently been linked with Kristijan Jakic while Al-Ittifaq have had no rumoured targets.
