Arsenal are allegedly lining up a £6m bid for Dinamo Zagreb youngster Tin Jedvaj.
The Gunners are hoping to snap up the highly-rated defender after his proposed move to Roma broke down, according to The Sun.
Jedvaj, 17, has already been called up to train with the Croatian senior squad and has been tipped to make his international debut soon.
Arsenal are also said to be in the hunt for Swansea City captain Ashley Williams.
