Carroll was among the most high-profile absentees from Gareth Southgate’s party for games against Germany and Lithuania.
In arguably the most notable selection, 34-year-old Sunderland striker Jermain Defoe was preferred to Carroll and Arsenal pair Theo Walcott and Danny Welbeck.
Southgate justified Carroll’s absence by saying the West Ham striker had not played enough this season – making 15 Premier League appearances in which he has scored six goals – but Kouyate is not convinced his team-mate should have missed out.
“For me, I don’t understand why England don’t call Andy because he has scored a lot of goals, but that is down to the manager,” Kouyate told talkSPORT.
"Maybe he will be called in the next international break."
Carroll earned the last of his nine England caps in 2012 in a World Cup qualifier against San Marino.
