A former trader at Goldman Sachs is angry that his 2010 bonus of $8.25 million fell way short of what he claimed his performance merited, and is claiming the US firm owes him more than $21 million, media reports said.

The case involves that of Deeb Salem, 35, reports said. He filed an arbitration complaint last year.

He said he helped the bank in billions by betting against the mortgage market in 2010, Bloomberg reported.

A spokesperson for Goldman Sachs described his claims as “utterly ridiculous”.
