Gareth Southgate says Mason Mount earned his England call-up 'on merit' but admitted he will use the upcoming European Championship qualifiers as an opportunity to plan for the future at right-back.
Southgate said Mount had been included on form but admitted he was actively looking to the future elsewhere, with right-backs Wan-Bissaka, Trent Alexander-Arnold and Kieran Trippier picked at the expense of 29-year-old Kyle Walker, who has 48 caps.
"Mason Mount's been one of the outstanding players in the league already this season, so we brought both him and Maddison in last October as much for the experience as anything," said Southgate, adding that he was keeping tabs on Mount's Chelsea teammate Tammy Abraham, who scored twice against Norwich last weekend.
"This time in particular, in Mason's case, as the younger one, he's in on merit. Simple as that. He looks like he's threatening the goal every game he plays.
"I've watched him develop through our youth teams since he was 16 and he's been an outstanding player at every age group.
"He's not in on the back of three games at Chelsea.
"He's in on the back of a year in the Eredivisie, which was outstanding; a very successful year with Derby County; European Under-19 champion with us.
"So he keeps improving and achieving at every level he is tested at, and that has been the same at the beginning of this season."
