Arsenal midfielder Matteo Guendouzi was recommended to Hertha Berlin by former Gunners defender Per Mertesacker, according to the Bundesliga side's sporting director.
The 21-year-old made the switch from England to Germany on a season-long loan on deadline day in October after falling out of favour with Arsenal boss Mikel Arteta.
And Hertha Berlin's Arne Friedrich has revealed that his former Germany international team-mate Mertesacker pointed him in the direction of Guendouzi in the summer.
