Another summer transfer window is well under way and Arsenal' Premier League rivals are busy cutting deals here, there and everywhere.
Jose Mourinho has already sealed two big signings in Diego Costa (not officially confirmed) and Cesc Fabregas with more big names on the way.
Manchester United, who do not actually have a manager at the moment, have also all but sealed a deal for Luke Shaw while big names continue to be linked with a move.
Meanwhile, over at the Emirates Stadium, the same second-rate dross continues to be linked with a move to north London. While Mats Hummels is Manchester United's main target, Arsenal are being linked with Tottenham reject Steven Caulker.
It is hardly inspiring stuff from Wenger, who reportedly has £100 million to spend in the transfer market.
So, without further adieu, we give you five reasons why Arsenal fans should be fuming with Wenger already this summer.
