Egypt midfielder Mohamed Elneny was warmly welcomed by Arsenal's official Facebook page, which changed its cover photo with one of the newly-signed player wearing the Gunners' kit.
The 23-year-old Mohamed Elneny was unveiled as Arsenal's first January signing on Thursday.
English reports said Elneny had penned a four-and-a-half year contract to become the first Egyptian to join Arsenal, who are seeking to win the elite Premier League for the first time since 2004.
Arsenal's Facebook page is flooded by Egyptian comments in the same way Chelsea's page was when Mohamed Salah, Elneny's ex-teammate at Swiss side Basel, joined the Blues in January 2014.
Elneny's cover photo on Arsenal's page was also accompanied with 'Elnenysigns' hashtag in English and Arabic.
Elneny, who is a product of the youth academy of Cairo giants Ahly but made his name with fellow Egyptian club Arab Contractors, joined Arsenal from Basel for a reported fee of seven million sterling pounds.
