Stephen McPhail is eager for Aaron Ramsey to stay at Cardiff as the promotion chasers head into the Championship run-in.
The 20-year-old's initial deal ended after Saturday's 2-0 win at Hull, making it 14 points from 18 in Ramsey's six games so far.
Cardiff boss Dave Jones has asked Arsene Wenger to let the midfielder stay in Wales until the end of the season with a 24-hour recall clause and McPhail hopes the Arsenal chief accepts that arrangement.
But the Irish midfielder reckons that, even if Arsenal refuse to let Ramsey extend his loan, the Bluebirds would still have enough in their squad to secure a place in the top flight.
"We would love him to stay," he told the Daily Star. "There are going to be 12 big games for us and if we have quality players like Aaron in the squad, then that's what we want.
"He can make a difference, but if he stays or goes, we feel we are strong enough and ready for this run-in. We have to get on with it if he doesn't come back."
Cardiff already have Jay Emmanuel-Thomas on loan from Arsenal until the end of the season and the 20-year-old sealed victory at Hull with his first goal for the Bluebirds.
Michael Chopra had broken the deadlock with his third in three games, and with Jay Bothroyd and Craig Bellamy also in attack, Cardiff are eyeing automatic promotion.
"You look at Jay, Chops and Bellers and if you can't get goals with those three, there's something going wrong," he added. "We are confident we can go up."
