Brighton have signed Viktoria Plzen defender Ales Mateju.
The 21-year-old Czech under-21 international joins on an undisclosed terms on a three-year contract.
The defender has been a regular for top-flight Plzen over the previous two seasons and helped the club win the Czech championship in 2016.
Manager Chris Hughton said, "Ales already has good experience playing regular senior football in his homeland - and has played Europa League football as well as the qualification phases in the Champions League.
"He has good experience for his age and the stage of his career he is at; we are delighted to welcome him to the club and the plan now is to break into the first-team group.
"Initially we will monitor his progress in training over the coming weeks, and then make a decision in terms of what is best for Ales's development - and one of the options might be for him to go on loan in order to continue playing regular senior football."
