Naismith will line up against Celtic on Sunday

The 20-year-old Scotland international is now looking forward to the season ahead with the Ayrshire side.

"I made the request after a period where I was becoming more and more frustrated with claims of mystery bids being made," he told The Sun.

"I understand I'm viewed as a commodity by the club, but I'm also a person who has feelings and emotions."

Rangers failed with repeated offers for Naismith over the summer, while Celtic enquired about a possible move.

However, Kilmarnock manager Jim Jefferies claimed the Scottish champions had failed to follow up a verbal offer.

"I would like to apologise to the Killie fans for my actions," added Naismith.

"I hope they understand I've felt under considerable pressure, especially after numerous promises that my situation would be resolved proved to be nothing more than false dawns.

"I've always strived to do my best for this club and my commitment while I am a Kilmarnock player will never waver."

Naismith, who is under contract until 2010, claimed his frustration was exacerbated by being kept in the dark.

He said: "When I asked for more information regarding these bids, little or none was given, especially regarding offers which were claimed to be in excess of £1.5m.

"The only bid I was advised of was Rangers' £1.5m offer.
