Oakwell exit for Tykes quartet

But defenders Rob Kozluk and Luke Potter, strikers Jon Macken and Michael Coulson and goalkeeper Luke Steele, who are also out of contract, have been offered new deals.Brazilian centre-half Souza has been a regular in manager Simon Davey's starting line-up since arriving from Belgian side Charleroi in time for the 2007/8 season, making a total of 78 appearances for the Tykes.Full-back Van Homoet signed on a free transfer from Sparta Rotterdam in June 2007, but has failed to hold down a regular place in the side, while Leon, a former Real Madrid youth-team player, has been a key member of the Tykes' midfield since arriving from Grasshoppers Zurich in January 2008.Letheren has been a regular for the Tykes reserves for the last two seasons, but has been unable to force his way past first-choice goalkeeper Heinz Muller and Steele.
