Mikel Arteta believes that a mentality shift is one of the reasons behind Granit Xhaka's purple patch in front of goal this season.
The former Arsenal captain, 30, has been influential in the Gunners' surprise title bid this term and has enjoyed his most productive campaign ever in front of goal after chipping in with seven goals and five assists in all competitions.
Xhaka has flourished after being handed a license to roam by Arteta and heads into Sunday's seismic showdown against Liverpool with four goals and an assist to his name from his last five matches for both club and country.
