Derrick attacks Glamorgan
Elliott produced a solid return in four matches, but Maher is averaging 15 in the Championship and Wright left early after picking up an injury. Derrick claims that the club have dramatically changed their tune since last season, where he and Robert Croft were criticised for their overseas players even though Mark Cosgrove, the South Australia batsman, averaged over 50.
"He [Wright] had been injured in Australia, and he certainly didn't look fit in the games I saw him in with Glamorgan," Derrick told BBC Sport Wales. "Overseas players have to set a tone and we have not been getting that."
Last year the club was struggling to afford overseas players until money was found to recruit Brendon McCullum and this season a fan helped pay for Maher's return after previous stints with Glamorgan in 2001 and 2003.
"If they were genuine supporters, why not give the money to the club and allow them to choose who they need?" said Derrick. "I've got nothing personal against Jimmy, but he wouldn't have been my choice and he's proved that with his performances.
"Last year we were told that there was no money for an overseas player, then at a meeting we heard that cash had been produced to bring Brendon McCullum over for the Twenty20. I was director of cricket at the time and knew nothing about it, that really put my back up."
