Arsenal have reportedly expressed an interest in signing Manchester United defender Phil Jones but manager Jose Mourinho made it clear that he doesn't want to sell players to one of his rivals.
The Gunners desperately need to add a new central defender before the end of the summer transfer window.
Attempts to sign Napoli's Kalidou Koulibaly and Valencia's Shkodran Mustafi have failed and manager Arsene Wenger has turned his attention to different targets.
The Frenchman confirmed at the end of last week that he will sign a new player before deadline day.
"It doesn't cost a lot of money, that," he told reporters.
"Why do you say I'm reluctant, I don't understand that? If I buy you tomorrow for £45m that means I've bought you for £45m, have I done well? Yes, if I listen to you, I will have done well because I spent the money. That is not a quality, buying a top player, that is different - and we are ready to do that.
"I spend £300m if I find the player and if I have the £300m. Not to forget as well that we are a club who has 600 employees who we need to have a responsible attitude for as well.
"It's a bit surprising that you come out of football games and you don't speak about football, you have to speak about money.
"I believe that you have to respect the players who play, the performance that has been done today by those teams and if you find players who can strengthen our team, then we are not reluctant to spend the money."
