Arsenal have made their first moves of the summer transfer market by the arrival of Sead Kolasinac on a five-year deal.
The Bosnia and Herzegovina international will arrive on a free transfer on July 1, when his contract at Bundesliga outfit Schalke expires.
The 23-year-old is the Gunners' first new face since Arsene Wenger finally confirmed his own future by signing a two-year deal, with the manager since outlining his aim to sign three players this summer.
Monaco star Kylian Mbappe is another target, with a £87million bid - double Arsenal's £42m transfer record - already rejected by the Ligue 1 champions.
Arsenal confirmed the move with a short statement, while Schalke added on their own website: "In his 123 Schalke games, the left back played with full effort and commitment, taking on a starring role over the last season."
