Arsenal manager Arsene Wenger hopes midfielder Mathieu Flamini could be fit for Sunday's Premier League clash with Chelsea with Cesc Fabregas' absence likely to continue. Flamini, Robin van Persie and Abou Diaby could all be involved in the crucial fixture but midfield talisman Fabregas and Belarus international Alexander Hleb are still not fully recovered. 'The one who has a realistic chance is Flamini,' Wenger told arsenal.com after his side's defeat by Middlesbrough yesterday. 'One who could be in the squad is Van Persie. Diaby could be in the squad as well. 'We don't know about Cesc and Hleb.'
