BURNLEY unveiled their fourth and fifth summer signings yesterday, but manager Owen Coyle revealed: “We’re not finished!”

Full backs Brian Hamilton and Richard Eckersley arrived in time to join their new team-mates as the Clarets’ set off for their pre-season tour of America this morning.

But after also adding defenders Tyrone Mears and David Edgar, and breaking the club transfer fee to bring in Scotland striker Steven Fletcher from Hibernian for £3million, Coyle insisted there would be no let-up in his quest to strengthen for the Premier League.

“For me we’re not finished. We’re putting it together and what we’re trying to do is invest in young players who we believe can go on to play at the highest level,” he said.

“I’m still looking to add to what we’ve got. If the right player becomes available in the right circumstances then of course we’re going to be interested because we’re always trying to move the football club on at every given moment.

“There never is an ideal number (of signings) because a few things need to come to bear; finance obviously being one of them, the availability and what’s involved in it.

“Whether it’s down the route of a loan player or the right player at the right price or a Bosman, it has to be the right type of player for what I want to do at the football club.”

Burnley are reported to be offering a trial to Ecuador international Fernando Guerrero while training in Los Angeles.

Coyle neither confirmed or denied any interest in the 19-year-old midfielder, who plays for Real Madrid Castilla.

“There are a number of players of different nationalities that we might be interested in,” said the Burnley boss.

“Whether we’re able for someone to join us in America for a bit of training then I’ll wait for confirmation of that. But we’re always looking to improve the squad.”

However, Coyle hit back at claims an “underhand tactic” was used to “unsettle” Sheffield Wednesday striker Marcus Tudgay.

The Clarets followed up a verbal offer for the 26-year-old earlier in pre-season with an official £1.5million bid, rising to £2m with add-ons. But after rejecting it yesterday, Owls chairman Lee Strafford slammed both Burnley and Tudgay’s agent, Darryl Powell.

"It's disappointing that an agent would act in such a cavalier manner when he is supposed to be protecting the interests of the player and also the right of the club to protect its assets. Sheffield Wednesday will not be taken advantage of in this situation,” he said.

"Marcus has stated that he is happy at Wednesday and has a good working relationship with Brian Laws. We would like Burnley to act in a more realistic and respectable manner so that we can get on with preparing for next season.”

Sheffield Wednesday described Burnley’s official offer for Tudgay, who is in the last year of his contract, as “derisory”, but Coyle said: “We’ve certainly not been underhand. Sheffield Wednesday will consider that a derisory offer from there point of view. I don’t. I think it was a fair offer, it was made with the best intentions and if Sheffield Wednesday feel fit to slander our good name then that’s up to Sheffield Wednesday.

“I don’t want to get involved in what one said or what the other said.

“We felt it was a fair offer, we never ever had any intention of unsettling any player at any football club.

“We made a fair offer verbally and all we did was put it in writing and increased the add-ons when we put it in writing.

“The total deal was £1.5million with £500,000 in add-ons, which I thought was a fair deal for a player with a year to go of his contract. Sheffield Wednesday thought otherwise and they’re well within their rights to do that.

“But I’ve got no thoughts whatsoever about having a pop at Sheffield Wednesday.

“They conduct their business as they see fit and we do ours.

“I think it’s probably the first derogatory remark we’ve had at this football club about anything.

“I can understand where they’re coming from; they’ve got a very good player that they want to keep hold of, and if they tell me that offer’s been turned down then it’s been turned down, and so be it.

“The easiest thing is to criticise others. That’s not my style. They can say whatever they want, we’ll continue to conduct our business in the manner we see fit.

“The offer’s been rejected. It won’t be improved upon.”
