Southampton have completed the signing of Serbian playmaker Dusan Tadic from Dutch side FC Twente.
The 25-year-old joins the Saints for an undisclosed fee, reported to be in excess of £8million, and becomes the first player brought in by new manager Ronald Koeman.
Southampton are looking to rebuild the squad following the sales of key men like Luke Shaw, Adam Lallana and Ricky Lambert after Mauricio Pochettino left to take over at Tottenham.
Attacking midfielder Tadic, 25, scored 16 times in 33 league games last season for Twente, as the Dutch side finished third behind Ajax and Feyenoord.
Tadic, who has agreed a four-year deal at St Mary's, is confident he has joined a club going places under Koeman, who impressed while in charge of Feyenoord in the Eredivisie.
"I watched a lot of the games last season and saw that the club plays really nice football which will suit me because I like to play in the same way," he added.
"The manager obviously knows me from the Dutch league so when he called me and told me his plan it was an easy decision to make.
"I know the manager well because he is one of the biggest Dutch legends in football, everyone knows him.
"He is a really good coach and you can always expect his teams to play well because he is leading them and because he is so good tactically. I am really excited to start playing for the club."
