ARSENAL plunged into crisis last night in the wake of Robin van Persie’s £22million move to Manchester United.
First Arsene Wenger admitted it may be impossible to replace him after his side limped to a goalless draw with Sunderland.
Then Arsenal’s boss revealed Alex Song will join Barcelona today after demanding to quit.
Wenger said: “Song expressed the desire to go to Barcelona. It is frustrating, we have learnt to deal with that but it’s always difficult to talk about things that happen internally.
“I never denied we lost a world-class player. Don’t get me wrong. Robin is very difficult to replace.”
Song is set to complete a £15million move to the Spanish giants.
Arsenal struggled without RVP and Song on an opening day of the season which saw both Fulham and Swansea smash FIVE goals.
New strikers Lukas Podolski and Olivier Giroud failed to impress.
Cameroon star Song, 24, has jetted out to the Catalan capital to have a medical.
He is the latest fed-up star to quit the Emirates — hot on the heels of RVP, Cesc Fabregas, Samir Nasri and Gael Clichy.
Wenger added: “The financial potential of some clubs is massive and that makes a difference.
“But we decided to sell Song as we have Jack Wilshere back from injury in one and a half months.
“We have Abou Diaby who has come back, Tomas Rosicky is not far away and we might bring another midfielder in as well.”
That is likely to be Real Madrid’s Nuri Sahin. Wenger, though, said: “You have to be patient a little bit over any new signings.”
Wenger was pleased with the impact of Santi Cazorla, who recovered in time from playing for Spain in midweek.
The French boss said: “It is difficult not to be pleased with him as he played the whole game in Puerto Rico. All of our chances were created by him, basically.”
Danish Striker Nicklas Bendtner is also likely to leave before the transfer deadline.
