Glamorgan fast bowler Graham Wagg is targeting the wicket of former captain Alviro Petersen when Essex visit the Swalec Stadium on Wednesday.
Glamorgan had wanted South African opener Petersen to return as a Kolpak player this season but he opted to join Essex on a short-term deal.
"He's a massive lbw candidate as everyone knows on paper," said Wagg.
"That's how I've been getting my wickets this season so it would be nice to get him as well."
Wagg added: "It's nice to see former team-mates doing well around the country when you're not playing against them.
"But when you cross the line at the Swalec Stadium there's no friends out there.
"I'm going out to get as many wickets as I can including Alviro Petersen."
Glamorgan coach Matthew Mott previously said he felt let down by Petersen's decision to leave Glamorgan.
And although Mott insists Glamorgan have moved on, he says his side will "cherish" taking the wicket of their former captain.
"That's months ago. We're well and truly over that and he's [Petersen] welcome back as a former captain of the club," Mott told BBC Wales.
"Obviously we'll cherish his wicket and hope to knock him over cheaply in both innings.
"But certainly there's enough players to worry about without singling out one player."
Glamorgan have endured a tough start to the season and are currently bottom of the County Championship.
They have lost to Leicestershire and Derbyshire fairly comprehensively and despite a better batting performance against Hampshire - Ben Wright getting the team's first century of the campaign - they only lost from the penultimate ball of the game.
The county's most recent clash with Gloucestershire was a four-day wash-out.
"The guys have been chomping at the bit to get out and play some good cricket," said Mott.
"We felt at the end of the Hampshire game we were starting to get nearabouts what we'd planned for and this game represents another opportunity to do that.
"The good thing is Kent's on top of the ladder with only one win," he added.
"So there's plenty of opportunity to climb up that ladder very quickly if we can string some wins together, and that's something we intend to start this week."
Glamorgan have decided not to risk all rounder Jim Allenby's back problem ahead of their Pro40 campaign, and have named an unchanged 12-man squad to face Essex.
Glamorgan team: GP Rees, NA James, WD Bragg, SJ Walters, BJ Wright, MC Henriques, MA Wallace (captain), GG Wagg, DA Cosker, HT Waters, WT Owen and MT Reed.
