David Luiz has returned to full training following a neck injury ahead of schedule, in a boost for Arsenal and manager Mikel Arteta.
The Brazilian defender signed a contract extension last season and remains a key first-team player for Arteta's FA Cup holders, despite making a number of high-profile errors that have led to fierce criticism from fans and pundits.
Luiz however is a popular and respected member of the first team at Arsenal, which meant his recent suffering of a neck problem, which threatened to keep him out for a period of matches, was a real blow for the Gunners.
