The 25-year-old defender is entering the final year of his contract at the Reebok Stadium and Gunners boss Wenger has been consistently linked with the England international. Wenger is keen to bolster his defensive options - he is also thought to be interested in Everton's Phil Jagielka - and has money available following the departures of Cesc Fabregas and Samir Nasri. But Trotters boss Owen Coyle says the two clubs are a distance apart in terms of their valuation of Cahill. He said: "There was a conversation between (Bolton chairman) Phil Gartside and a representative of Arsenal. "I'm only passing this on as a third party, but the word derisory doesn't even cover it. "When I make an offer for a player, I'd like to think in the right ball park, but this wasn't even close. "I spoke to Gary Cahill about it before the Macclesfield game, and he knows everything that's going on." Coyle continued: "It is nowhere near our valuation as a football club of Gary Cahill. "Gary's representatives had been made aware there had been a so-called offer, but given the amount that was talked about I don't call that an offer. "If I make an offer for someone I do it in writing so you know exactly where you are with it. "It is fair to say the dialogue was nowhere near what the football club would even consider for Gary Cahill to leave Bolton Wanderers." Wenger, however insists that the reported figure of £6million was incorrect. "That number is wrong," said Wenger. "It is completely wrong. I believe every negotiation is between two parties and you only have to sell the player if you are all right with the price. "In this case, the information is below what has been spoken about." Bolton chairman Phil Gartside re-tweeted a message sent by a Bolton fan angered by the offer. Wenger, however, was furious at Bolton's reaction. He said: "You only have to sell the player if you are all right with the price. It is not true. You can believe Gartside or you can believe me. It's not right. It's not the truth. "If Gartside can say I am lying, I am ready to confront him. The truth is that we never speak about our negotiations. "If a club doesn't want to sell a player, it can keep him. When we sign a player, we come out here and tell you and keep the price a secret. "They do not need to sell the player, they can keep him. If you ask do I want to buy your house and you are not happy with the price you say no, that's it. "Why should you feel insulted? I don't understand. If the player is not for sale, they can keep him. I don't understand the problem. "If we want to buy the player, we buy the player. I do not have to explain for how much." Coyle had said earlier in the summer that he was resigned to losing Cahill, but that he would only sell him if the right offer came in. While the former Republic of Ireland international believes the defender would fit in well at Arsenal, he has reiterated that he will not sell on the cheap. "I am very respectful of Gary's wishes in this as well," he said. "I totally understand he wants to play at the highest level and Arsenal are an elite club, a club I think he would probably slot in to with tremendous style because he is such an accomplished player. "He is more than capable of playing in a team of that stature. "But it has to be done at the right business for Bolton Wanderers Football Club. "It was way, way short and I must stress the word way as it was a million miles short of what Gary Cahill's valuation is." Coyle also confirmed that defender Marcos Alonso is facing eight to 12 weeks on the sidelines after suffering a broken metatarsal in the midweek Carling Cup win over Macclesfield. The Spaniard was making his first start since April but joins a defensive injury list that includes Tyrone Mears, Sam Ricketts and Gretar Steinsson. Coyle said: "Marcos has fractured a bone in his foot and he will have an operation this morning. "He will be out for eight to 12 weeks, which is a real blow for him because he was starting to get to grips with the English game. "He had a terrific pre-season and was pushing to try to get into the starting line-up."
