Arsenal are reportedly awaiting permission from Everton to hold talks with Marouane Fellaini after activating the release clause written into the contract of the Belgian midfielder.
According to Goal.com, Arsenal made a £22 million offer for Fellaini last Thursday, but have yet to be granted the opportunity to discuss personal terms with the player, and await a response from Everton.
Despite Arsenal meeting Fellaini's contractual clause, Everton have not made the Belgium international available and, until they do, the Gunners are unable to negotiate a proposed transfer to the Emirates Stadium.
Arsenal, however, are reported to be in no rush to push through a move as most of their staff - including their medical team - are on summer vacation and will not return to north London until the end of the month.
Should Arsenal be able to conclude a deal for Fellaini, the 25-year-old would become the club's record signing - serving as an early signal of intent from Arsene Wenger in the summer transfer window.
The Gunners manager will reportedly be backed with £70 million over the coming months, and the club's chief executive Ivan Gazidis claims Wenger will not be afraid to spend big in order to land his preferred targets.
"It is no secret that we think he [Wenger] has done a fantastic job and we think we can give him the tools he needs," explained Gazidis.
"When we are thinking about trusting someone with the type of money we will have, we can think of nobody better than Arsene.
"He is not scared to spend money, but he has to believe he is getting a top-class player.
