Arsenal pair Granit Xhaka and Bernd Leno are unsettled ahead of the summer market.
The Athletic reports Arsenal staff are growing concerned the experienced pair will push for a transfer in the summer.
Arsenal would be forced into recruitment if ex-skipper Xhaka, 28, and stopper Leno, 29, leave.
Arteta's decision to bring in goalkeeping coach Inaki Cana has also been questioned after his recommendation of back-up keeper Alex Runarsson.
Runarsson, 26, failed to impress when called up to replace Leno and the club later swooped for Mat Ryan, 29, on a free from Brighton.
