Arsenal's opening move for Bruno Guimaraes has been knocked back by Newcastle, according to Sky Sports, with the Magpies determined to hold onto their captain.
The Brazil international, 28, still has two years left on his St James' Park contract, and Newcastle have made clear they have no intention of selling their skipper this summer.
Despite the rejection, Arsenal are reportedly weighing up whether to return with an improved offer as they continue to explore reinforcements in midfield.
Guimaraes has become a key figure under Eddie Howe since arriving on Tyneside, and his leadership armband only underlines how integral he is to the club's plans. Newcastle's stance suggests any deal would need a substantial package to even be considered, let alone accepted.
For now, though, this looks set to be a standoff rather than a swift transfer saga — Arsenal must decide how far they're willing to go, while Newcastle dig in over one of their most prized assets.
