Arsenal boss Mikel Arteta has said Granit Xhaka deserves to relish in his turnaround in fortunes at the Emirates -- almost three years to the day since he was infamously booed off by the club's fans -- adding that he's unlocked something in his play and it's paying dividends on the field.

Xhaka scored a well-taken half volley to help Arsenal to a 1-0 win over PSV Eindhoven in the Europa League on Thursday and put them on the cusp of winning Group B.

"I think he has faced adversity, and in difficult moments he has put his arm up when he had something different to do," Arteta said in a postmatch news conference. "His worth ethic, the way he is as a person, the way he treats everybody around the club, and the love for this football club and the profession is unquestionable, and I think he fully deserves that.

"I'm really happy to see him enjoying his career."
