David Luiz failed to train with his Chelsea team-mates on Wednesday in a bid to push through a transfer to Arsenal.
The Blues centre-back has been in talks to leave Stamford Bridge his summer and is hoping to secure a move to north London.
The Gunners are in desperate need of strengthening their defence following the departure of Laurent Koscielny.
Arsenal have submitted a bid for Luiz – which the Brazilian is aware of – prompting him to make the decision not to train with Chelsea.
The transfer window slams shut on Thursday and the centre-back knows he is short on time to complete a move away
from south-west London.
