David Luiz apologises in emotional message to sacked Arsenal manager Unai Emery

David Luiz has issued a heartfelt apology to Unai Emery after Arsenal sacked their manager on Friday.

The Brazil international was signed by Emery on the final day of the summer transfer window in a £7million deal from Chelsea.

Luiz had worked under the Spaniard briefly at PSG and was recruited in an attempt to add experience and stability to an infamously porous defence.
