"We've had no enquiries and no offers. We had the same situation with Aaron Ramsey.
"We think it's quite good that players are getting spoken about at this football club because it means they must be doing something right and they must be doing well as players themselves."
Matthews has declared himself fit for the visit of Roy Keane's Ipswich after missing out on the 1-0 defeat at Barnsley last weekend with a groin injury picked up on U21 duty.
And Jones knows Cardiff need to get back to winning ways against the struggling Tractor Boys after picking up one point from their last three games.
"It's how we bounce back," said Jones. "We've gone from being the form team in this division to losing the last two games.
"We've tried to pin-point the reasons why. You can look at injuries and everything else, but we feel we've stepped off the mark in our work rate and quality in certain positions and we've got to get that right."
Cardiff manager Dave Jones
Fifth-place Cardiff are faring much better than Ipswich who are next to bottom in the Championship with just one win from 17.
But Jones insists he will not be handing out any sympathy to former Manchester United and Republic of Ireland international Keane.
"Roy doesn't want my sympathy or anybody elses," he added. "We all have a job to do.
"If I was in a similar situation, would Roy be thinking about me? No, and I'm not going to be thinking about Roy - and that's the right attitude to have."
