The Switzerland international has already agreed personal terms with the Gunners, as Goal exclusively revealed last week, and now it appears that the 23-year-old will finally get his much-anticipated move to Emirates Stadium after weeks of negotiations between Arsenal and Borussia Monchengladbach.
Talks between Gladbach sporting director Max Eberl and Arsenal's chief transfer negotiator Dick Law hit a stumbling block earlier in the week but now all that remains to sort out are the final 'intricacies' of the deal, with the transfer fee expected to be in the region of €43 million euros including add-ons.
Xhaka, who is joined in London with his brother and parents, will sign a four-year contract at Arsenal after completing his medical and has requested Francis Coquelin's no.34 shirt - with the Frenchman reportedly happy to accept and change his squad number ahead of the new season.
Arsenal boss Arsene Wenger identified Xhaka as a potential signing at the start of last season after being resigned to the departures of Mikel Arteta, Mathieu Flamini and Tomas Rosicky whose departures have left a gap in the Gunners' midfield.
Wenger's failure to buy an outfield player in the transfer window last summer received widespread criticism from Arsenal fans, and he aims to get the majority of his transfer business done before the club travel to the United States for their two pre-season games in San Jose and Los Angeles at the end of July.
Xhaka himself will meet up with the rest of the Switzerland squad for their training camp on Sunday, while the first match of Euro 2016 is on June 10th.
Interestingly, Taulant, who chose to play for Albania, and Granit, would be the first brothers to meet in a European Championship game when they face each other in next month's Group A clash.
