Arsenal manager Arsene Wenger on Sunday queried the arrangement that has allowed former Chelsea midfielder Frank Lampard to join Manchester City on loan from its sister club New York City.

As well as Lampard's move to the Etihad Stadium, New York has also loaned Spanish striker David Villa to Melbourne City. All three clubs are owned by the City Football Group, a holding company of City's owners, the Abu Dhabi United Group.

Wenger, whose side faces City in next weekend's Community Shield, suggested the partnerships could give the Premier League champion an unfair advantage.
