Manchester United are set to trial Aaron Wan-Bissaka at centre-half in preseason.
The Sun says United manager Ole Gunnar Solskjaer is keen to see the right-back in a more central role in pre-season matches to find out if he could handle the position.
Wan-Bissaka, 23, is their quickest and best tackler and could be ideal in the middle of a back four - or even right side in a three.
It would make United's backline more flexible if he could copy Kyle Walker at Manchester City and play both slots.
United are keen on Atletico Madrid full-back Kieran Trippier, 30, to provide competition at the back.
