London: Arsenal manager Arsene Wenger on Thursday said the English football club is working '24 hours a day' on transfers before the summer window shuts on August 31.

The 'Gunners' have roped in goalkeeper Petr Cech from arch-rivals Chelsea but potential targets such as French striker Karim Benzema and Polish footballer Grzegorz Krychowiak have said they would not make a move to the Emirates Stadium.
