Arsenal boss Arsene Wenger is confident a deal to sign Andrei Arshavin will go through, but the Premier League is not expected to ratify the switch until Tuesday.
The Zenit St Petersburg playmaker passed a medical and agreed personal terms with the Gunners on transfer deadline day, and looked set to secure the move before the 5pm deadline.
However, reports emanating from Russia suggested talks between Arshavin and Zenit over a final payment threatened to collapse the proposed switch.
Wenger, though, told Sky Sports News that he expected "positive" news to be announced later on Monday.
And in yet another twist in this protracted saga, a conclusion to the transfer is not expected to be finalised by the Premier League until Tuesday.
