BARNSLEY owner Chien Lee has announced his group have added to their portfolio of clubs by taking a stake in German outfit Kaiserslautern.

Lee and fellow Reds co-chairman Paul Conway have reportedly taken a ten per cent share in the German third tier club as part of a consortium which also includes baseball club Tampa Bay Rays co-owner Randy Frankel.

Kaiserslautern have fallen on hard times recently, having won their fourth German title in 1998 and competed in the Champions League.

Lee and Conway already own Barnsley, French second division team Nancy and Danish second tier outfit Esbjerg - with all three in danger of dropping into the third tiers this season.

They also have stakes in Belgian top flight club Oostende, Swiss club Thun and Den Bosch in the Netherlands.

They have previously owned OGC Nice in the French top flight.

Lee tweeted: “We completed the investment in FC Kaiserslautern, one of the most historic clubs in Germany and is our 8th investment in the European football.”
