Unai Emery has been given just a month to save his job with Arsenal chiefs fearing he’s “drained the DNA” from the club.

Now, according to The Sun the under-fire Spaniard has until the New Year to turn things around at the Gunners ahead of a favourable run of Premier League fixtures against Southampton, Norwich, and Brighton.

The official line from the Emirates is that Emery still has the “100 percent support” of head of football Raul Sanllehi and technical director Edu.

But Arsenal are without a domestic victory since the first week in October and have slipped down to sixth in the table, meaning their hopes of Champions League qualification are decreasing by the week.

According to the Mirror, some staff fear that Emery faces an impossible task to ­revive a club that has destroyed Arsene Wenger’s legacy through a series of disastrous high-level ­appointments.

One source told the outlet: “The DNA that made ­Arsenal the club it was has slowly but surely drained away.

“Appointments have been made – both before and after Wenger’s departure – that either didn’t work out or aren’t working out.

“Long-serving members of staff have been shocked by what’s ­happening to the club.”
