David Ornstein understands Arsenal may look to bring in a right-back who can also play as a centre-back this summer.

Arsenal have had some defensive issues in the latter part of the current campaign, with injuries to William Saliba, Takehiro Tomiyasu, and now Oleksandr Zinchenko, causing some problems.
Saliba’s injury was particularly problematic because of Tomiyasu’s absence, with Arsenal unable to shift Ben White across into a centre-back role because of the lack of cover on the right.
Tomiyasu himself could even have played at centre-back if he’d been fit.
But Tomiyasu’s fitness is evidently not something Arsenal can rely on, pushing the club to make summer additions.
“So do Arsenal look to bring in somebody at right-back?” Ornstein began, speaking to FIVE.
“I’ve heard suggestions (they could look for somebody) maybe that can also play at centre-half as well if needed. An auxiliary centre-back/right-back who can play in both, not too dissimilar to Tomiyasu.”

Of the recent media links, perhaps the speculation around an Arsenal move for RB Leipzig’s Mohamed Simakan makes the most sense here.
Ed Aarons of The Guardian reported that Arsenal were showing strong interest in Simakan, ahead of the summer transfer window.
Fabrizio Romano then confirmed that Arsenal had sent scouts to follow the player on multiple occasions, and Simakan is “appreciated” by the club. But there’s nothing advanced or imminent at this stage.
Simakan has split his time between centre-back and right-back this season with Leipzig, making 34 appearances in all competitions, scoring three goals and providing eight assists.
The 23-year-old had also played out on the right at times in his early days at RC Strasbourg.
