Patrick Vieira believes international football will aid the development of Marc Guehi, who is looking to help Crystal Place reach the FA Cup semi-finals before joining up with England.
Having spent last season on loan at Championship side Swansea, the 21-year-old made a permanent exit from Chelsea in the summer and has impressed since arriving at Selhurst Park.
Guehi's performances for the Eagles this week led to his first senior international call-up as England kick-off their World Cup preparations with friendlies against Switzerland and Ivory Coast.
Former France star Vieira was delighted for the England Under-21s captain, who takes this step at an exciting time for club and country.
