SC Paderborn sports chief Martin Przondziono insists they won't be pressured into selling Streli Mamba.

The youngster is being linked with a January move to West Ham.

But Przondziono says they're under no pressure to sell.

With a contract until 2022, Przondziono says: "We decide alone what happens to him..."

Mamba has scored five goals in nine games so far this season.
