Arsenal are reportedly considering an approach to sign Ryan Bertrand from Southampton this month.
Bertrand has accumulated more than 200 appearances for the Saints in his career, but his future is uncertain with his contract expiring in the summer.
So far, there has been no progress in the negotiations over a new deal and Standard Sport claims that the Gunners may look to sign him.
Maitland-Niles, meanwhile, has not been able to provide the same creativity as Tierney and hence, Bertrand has been identified as a possible target.
Still, it may be difficult to convince the Saints to sell him, considering they have no other senior options for the left-back spot.
A deal may be dependent on whether the south Coast outfit can find a suitable replacement for the ex-Chelsea man in the next 10 days.
