Walker, a Unitedite, has cemented his place in the Blades' backline after Gary Naysmith was ruled out due to injury. Namesake Kyle Naughton in recent games has switched to Naysmith's position (left-back), whilst Walker took the available right-back duty.
The-18-year-old has two international caps for the U19'S national side, when he was rewarded with a call-up earlier in the year. Bosnia Herzegovina, Scotland and Slovakia are England's opponents in late May early June.
Well done Kyle!
