Globe Trotter: Cahill (right) could be set for a switch to the Premier League's big guns
However, having seen Blackburn's England Under-21 star Phil Jones join Manchester United in a deal which could be worth ?20million, Coyle is well aware of the value of his centre-back.'I believe he could play for any club - I'd put my reputation on it.'There's been a lot of interest - and you don't have to be a genius to work out some of the top clubs in this country have been interested - but nothing concrete yet.'It would take a lot of money. It is up to those clubs to put something firm to the chairman.'He is not a player we want to lose, I have to stress that, but we have to accept if it is the right deal for the club and the player it has to be done and that then frees up cash for us to invest in the club.'I would love him to stay. He is a fantastic player for the club and I am not saying I want him to go, but if he does it will be the right business for the club.'
Staying put: Coyle is keen to keep a hold of his England international
If Cahill were to leave, likely for a fee in excess of ?15million, Coyle is keen to plough that money back into bolstering his squad.The Bolton boss has made considerable progress since taking over in January 2010 but is keen to push on further.He accepts, however, the club have to be on the ball with their transfer business if they are to stand a chance of beating rivals with bigger budgets to their targets.'I am in the market to improve the club and I am looking to make sure we get the right quality to add to the squad and take the team forward'We have to make sure when we have targets we are first on the scene for them because if we arrive at the same time as Chelsea or Manchester United we will lose out.
Club and country: Cahill recently made the breakthrough into the England squad
'There comes a time when you are a manager when you need some help and finances might need to be made available.'Hopefully we can add. There has been tremendous progress as we were a team favourites for relegation when I joined.'We hope to have a couple of new faces in by the time we start pre-season on July 4.'
Loan star: Sturridge who starred on his loan at the Reebok could return for a second spell
Having brought in Chelsea striker Daniel Sturridge on loan for a successful second half of the season Coyle has been linked with returning for a permanent move.It remains to be seen whether the Stamford Bridge side are prepared to sell but Coyle offered a word of warning to the England Under-21 international.'We would love to have Daniel back at the club but he may be in Chelsea's plans.'Given the development Daniel has made he has to keep playing - it would be detrimental for him to be sat on the bench.'
