Arsenal manager Arsene Wenger has ruled out the club improving their resources at centre-back during the summer transfer window.
Laurent Koscielny, Per Mertesacker, Gabriel Paulista and Calum Chambers are players currently available to Wenger in the position but a number of injuries this season have often seen the Gunners threadbare at the back.
But Wenger has no intention of adding to his centre-back options despite the constant injury worries and says full-backs Mathieu Debuchy and Nacho Monreal can fill in if need be for Arsenal.
"Four is enough," Wenger said of his available options. "[Mathieu] Debuchy can play there, [Nacho] Monreal can play there, so you can say we are not out to buy a central defender. And Gabriel will be a great central defender, believe me."
Wenger's confidence in his defenders stems from his intention to move Chambers to centre-back in the long-term, after spells at full-back and midfield.
The ex-Southampton youngster arrived at Arsenal with a reputation of being versatile but after just one season at the Emirates Stadium, Wenger feels the 20-year-old is best off remaining at centre-back.
Hector Bellerin's emergence this season coupled with the imminent return to Arsenal of Carl Jenkinson from a season-long loan spell at West Ham United means Chambers's opportunities to play at right-back are set to dwindle from next term.
"First, his stature [suits that position]," the French boss explained. "The fact he is intelligent and reads the game well, the fact that he's more at ease in the middle.
"On the flank, today you need more pace, more change of direction, more agility. He has the stamina, the power and the quality to be a central midfielder or a central defender.
"He's pretty much there. At the moment I have players who have more experience than he has [at centre-back], but in pre-season I will play him there."
