Arsenal transfer news: Next Gunners manager told to ‘consider’ Barcelona deal
Bellerin was linked with a move away from Arsenal to the Nou Camp last summer.
Barcelona are yet to settle on a replacement for legendary right-back Dani Alves, who left the club in 2016.
Sergi Roberto and Nelson Semedo have been tried but Barca have been regularly rumoured to be keen on Bellerin.
Karen says Bellerin may not be the only first-team player who could leave Arsenal this summer.
He says centre-back Shkodran Mustafi and midfielder Granit Xhaka may go, but admits it depends on who the next manager will be.
“It depends a little bit on the new manager coming in and what style of football he wants to play,” Karen told ESPN FC.
“I would say Shkodran Mustafi might be one player they may be willing to replace.
“But given Laurent Koscielny’s injury now, they may be more inclined to keep hold of him.
“If Barcelona come back with another offer for Hector Bellerin, I think that’s something they should consider and maybe buy a right-back who is more defensively-oriented than Bellerin is.
“Other than that, Granit Xhaka, he’s had his ups and downs this season but it’s possible that the new manager could get more out of him.
“So it’s hard to say exactly who’s going to fit into this new system.”
