Robin van Persie and Gael Clichy will miss the
first leg of Arsenal's Champions League clash with rivals
Manchester United next week.

Dutch striker van Persie has groin trouble while Clichy
remains sidelined with a back injury.
But Arsenal manager Arsene Wenger has confirmed goalkeeper
Manuel Almunia, defender Johan Djourou (knee) and striker Emmanuel
Adebayor could all be in contention for Sunday's clash with
Middlesbrough.
"We will rotate a little bit again, but we have no major
injuries from Liverpool," Wenger told Arsenal TV Online.
"Manuel Almunia was in full training on Thursday and we will see
how he responds. Djourou was in full training also so we will see
how he is too. Both could come back into the squad.
"It is not enough training to say [for sure] yet, we need 48
hours more. Emmanuel Adebayor should come back into training on
Saturday. He could be in the squad.
"But Robin van Persie is definitely out for Sunday and for
Manchester United.
"Gael Clichy could be back for the second Manchester United
game. He has a scan on Monday. We'll go from there. He has a chance
to be back in full training next week."
