Speculation linking the Clarets with a renewed bid for Riordan is old news, according to Coyle.

Coyle failed with a £400,000 offer for the Scotland international back in January.

And the former Hibernian man was part of a package put together by the Parkhead club to try and lure Kyle Lafferty, which was turned down, before he completed a move across Glasgow to Ibrox.

The 25-year-old's name has refused to go away, as Coyle looks to add to the four new faces he has landed so far.

But I understand Riordan will not be a fifth, for the time being at least.

Coyle said yesterday afternoon: "We have put an offer to someone, and we are waiting for them to come back to us.

"But it is certainly not Derek Riordan.

"The last contact I had with Celtic was when they were in for Kyle Lafferty, and obviously Derek Riordan was part of that deal.

"But I've not had dialogue with Celtic since.

"Derek Riordan is a player I've always admired, since he came through as a young kid, because I think he's a talented player.

"And we did try to do something in January, but he is not the player we are talking to."

Burnley depart for their trip to the USA on Tuesday, and Coyle is hopeful of adding to his squad before then: "I've spoken to a couple of people as regards trying to entice them to come to the club, but there is nothing concrete to report.

"But there might be before we go to America."

Operational director Brendan Flood had confirmed Burnley were still keen on Riordan last month, saying: "He is definitely of interest.

"It's exciting. There are people who want to come to Burnley and we want to get the best players.

"But Owen (Coyle) doesn't want to make decisions, necessarily, that will keep the newspapers selling.

"He is better making the right decision for the team, and he is being very selective."

It is believed Burnley were quoted £1m for Riordan in January, who has another year left on his contract.

And even though reports suggest Gordan Strachan would accept a bid in the region of £750,000 for the player – who he is thought to want to move on before the Scottish champions return to training today at Lennoxtown – any deal appears unlikely in the meantime.

Coyle is a fan from his impressive spell at Hibs, where he hit 62 goals in 146 appearances, before his career stagnated at Celtic.

The Edinburgh-born Riordan has made only 32 appearances in two seasons for the Bhoys, scoring eight goals, since a £200,000 move in June 2006 – a fee reduced as his contract with Hibs was due to expire in October that year, and Riordan had already made a pre-contract agreement to sign for Celtic on a free transfer in the following January, 2007.

And a fall out with Strachan earlier this year did nothing to enhance his chances of a regular start, reporting Celtic to PFA Scotland for trying to fine him £1000 for failing to attend a supporters rally, before an outburst in the Scottish press, when he said: "I only get chucked on when we need a goal, so he (Strachan] must think I can get him one.

"He obviously does not want to do it unless he really has to, because he does not want me to prove him wrong.

"He knows I would score quite a lot if he played me as much as he has played the other strikers, but I don't think he wants to be proved wrong.

"When I speak to him, he's nice to me and says all the things that players want to hear about me being part of his plans, but you know by his actions that he is talking rubbish.

"It is frustrating. I've virtually chucked it at Celtic — what's the point when I'm not getting a chance?

"I feel let down by the manager. I remember him sitting in my mum's house trying to sign me and he said I could play anywhere in his midfield or up front. Now I can only play left midfield for some reason and that's not even my best position."
