Southampton have signed striker Grzegorz Rasiak for £2m from Tottenham.
Rasiak has scored four times in 12 games at Southampton
The 27-year-old Poland international has been on loan at St Mary's Stadium since February, teaming up with his former Derby manager George Burley.
He has agreed a four-year deal at Saints after hitting four goals in 12 games since his move.
"I have enjoyed myself here, I am happy and I think I have done OK so far," said Rasiak, who will formally seal the move when the transfer window opens.
"The team is playing much better and it is looking good for next season.
"I am very happy here and want to stay longer - and it has been good preparation for the World Cup which I am now looking forward to."
