Mikel Arteta said Granit Xhaka had made him a "better coach" as the Arsenal manager prepares to lock horns with the Sunderland captain on Saturday.
Granit Xhaka praised his side's "pure mentality" as Florian Wirtz's goal in the 11th minute of stoppage time snatched a 3-2 win for reigning champions Bayer Leverkusen at Borussia Moenchengladbach in Friday's Bundesliga opener.
Eyebrows were raised when Xhaka arrived from Premier League runners-up Arsenal at the start of last term, with Leverkusen coming off a fifth-placed finish and with rookie coach Xabi Alonso preparing for his first full season as a first-team head coach.
After years of heartbreak and being dubbed "Neverkusen" for their string of runners-up finishes, Bayer Leverkusen finally broke through to claim their first-ever Bundesliga title. Their 5-0 victory over Werder Bremen last week secured the trophy, marking a watershed moment in the club's 119-year history. Although they have enjoyed intermittent cup success, this league title signifies a shift in their fortunes.
