Worcestershire director of cricket Steve Rhodes says he has no animosity towards the two players who left to join Surrey three years ago.
Accusations of a bust-up between Rhodes and Gareth Batty surfaced after the former England spinner left, preceded by Steven Davies.
"That is history now. They moved three years ago. They have moved on," Rhodes told BBC Hereford & Worcester.
"We have moved on as well and it's just another game of cricket."
Batty was involved in an incident with a spectator when he returned to New Road with Surrey two years ago, but Rhodes says it is all about the players who will be playing in the game at The Oval, which begins on Thursday.
"I like beating anyone," said Rhodes. "Any victory is a huge bonus, but they are one of the wealthiest clubs.
"They spend a lot of money on players. At a club like ours, with the budget we have got, you have big extremes and that's one of the reasons we want to beat them.
"Their squad is a lot stronger than two years ago. They have no Chris Tremlett at the moment, but they will be leaving out a couple of decent bowlers.
"With the bat they played a very attacking game last year but they still have a couple who bat properly, as it were."
