Mark Cosgrove believes Glamorgan should make every effort to sign Simon Jones on a permanent basis.
Former England fast bowler Jones has joined the Welsh county on a month's loan deal from Hampshire.
And Glamorgan opener Cosgrove said: "I'd like to see him stay until the end of his career, that would be fantastic.
"He shows everybody in the team, everybody in the crowd, that he actually loves being here. He definitely wants to be here."
Jones started his career with Glamorgan in 1998, and he marked his return to the side by taking a wicket in the FL t20 defeat away to Essex on Tuesday.
Glamorgan and Jones have refused to discuss any possible extension to the bowlers loan spell and Hampshire insist the 2005 Ashes hero remains "a large part of their future plans".
But Cosgrove, who has signed for the duration of the Twenty20 campaign, says Jones has already had a positive impact on the whole squad.
"I think it took him five minutes to settle back into the Glamorgan colours," said the 27-year-old Australian.
"He's fantastic, he shows everything that you want in a player - especially a bit of passion, a bit of fire. He was really pumped up when he got that wicket [against Sussex] and tried to get the crowd going.
"He was a bit disappointed the crowd wasn't really behind us, they were a bit quiet. Hopefully next week when we're back home they'll be a bit louder."
Cosgrove has returned to Wales for his fourth stint with the county, having played in 2006, 2009 and 2010.
He was named the county's player of the year last season after topping the run-scorers chart with more than 2,000 in all competitions.
A much-changed Glamorgan setup awaited him following a winter of turmoil. Coach Matthew Maynard and captain Jamie Dalrymple both resigned in acrimonious circumstances in November.
Australian Matthew Mott succeeded Maynard and South African Alivro Petersen took over the captaincy, and Cosgrove says he has been hugely impressed by the way the players have responded to the upheaval.
"The changing room is awesome," he said. "It's a fantastic changing room, it's one you want to be in and want to be a part of.
"It's fantastic for all the boys all around the group - the second team are really striving to get into the first team.
"The boys have been really professional and just gone about their business really well. They are going really well in the four-day competition and we're going pretty well in the Twenty20 competition."
Glamorgan face Derbyshire in County Championship Division Two on Monday in Cardiff, before returning to T20 action on Friday against Surrey, also at the Swalec.
