Former Manchester United defender Mikael Silvestre has enjoyed a pop at Arsenal.
Silvestre, who Arsene Wenger signed from Manchester United in 2008 and made 43 appearances in the Gunners' defence, tweeted a tongue-in-cheek picture of an empty Arsenal trophy cabinet, calling on Patrick Vieira to return to the club to help his former manager.
Manchester City chief Vieira, who played 406 games for the club over nine seasons, is rumoured to be the favourite to replace Arsenal's head of youth development Liam Brady.
