Arsenal's signing of Andrey Arshavin is set to be discussed at a meeting of Premier League clubs on Thursday.
Arshavin only officially completed his move to Emirates Stadium from Zenit St Petersburg on Tuesday evening, almost 24 hours after Monday's 5pm transfer deadline.
The Premier League had stated on Monday that due to the inclement weather conditions they would allow the paperwork for some deals to be processed after the deadline, provided proof of an agreement could be provided.
The Gunners are currently outside the top four of the Premier League and Arshavin's signing is seen as crucial to their hopes of securing UEFA Champions League football next season.
Aston Villa hold a five-point advantage over Arsene Wenger's men and they are among the teams who are keen to discuss the Russia international's protracted arrival.
When asked about the Arshavin deal, Villa boss Martin O'Neill said: "I have nothing to say at this minute.
"Paul Faulkner (Villa director) has told me that there is a Premier League meeting on Thursday and some points are being raised.
"Not necessarily by us at Aston Villa. There just needs to be clarification on the extension."
