Brighton 1-3 Southampton: Dusan Tadic on target in Saints' victory
Southampton's summer recruits all featured as they beat Brighton 3-1 in their latest pre-season fixture.
One of those new arrivals, Dusan Tadic, hit his first goal for the club in the 19th minute, while Steven Davis made it two before the break.
James Ward-Prowse's powerful strike made it three just after the hour.
Substitute Kazenga LuaLua hit Brighton's consolation with 16 minutes remaining.
Southampton have sold five players for £92m this summer but have made inroads in the transfer market themselves with Tadic's arrival backed up by those of Graziano Pelle and Ryan Bertrand, both of whom were also named in the starting XI.
There was no place for midfielder Morgan Schneiderlin, who only returned to training this week after featuring for France at the World Cup and is a target for Tottenham.
