Arsenal are looking for big-name signings this summer - but will also look to bolster Mikel Arteta 's squad depth.
They want a top-quality defender, with Crystal Palace 's Marc Guehi among their more ambitious targets. But they could also look for a backup right-back, having lost Takehiro Tomiyasu to a long-term knee injury. Gunners scouts have made checks on Leicester 's Belgian full-back Timothy Castagne as one potential option.
He has also played at left-back during his three seasons with the Foxes and previously for Italian side Atalanta. Arsenal's other current backup right-back, Cedric Soares, is out on loan at Fulham and due to return to the Emirates with a year left on his contract.
