Manchester City are reportedly concerned about the consequences of Mikel Arteta's likely exit from the Etihad Stadium.
Having spent time as Pep Guardiola's assistant, Arteta has allegedly decided to accept an offer to become the new manager at Arsenal.
While no developments have been made official, it has been suggested that the Gunners plan to have the Spaniard in place for Saturday's Premier League fixture at Everton.
As far as City are concerned, the Daily Mail suggests that Arteta's expected departure has not gone down well behind the scenes.
The report claims that there are fears that City's form over the second half of the campaign may be affected should they not find an immediate replacement.
Guardiola has confirmed that talks are ongoing between his right-hand man and the North London outfit.
