England Under-21 boss Aidy Boothroyd will join the senior squad at the World Cup.
The 47-year-old former Leeds United coach travels to Russia with Gareth Southgate’s side on Tuesday as England continue to integrate their age-group coaches at different levels.
Yorkshireman Boothroyd’s involvement had been planned for a while, before he guided England Under-21s to a third successive Toulon Tournament title at the weekend.
The former Huddersfield Town defender will not join the coaching set-up in Russia, with England due to play their World Cup opener against Tunisia in Volgograd next Monday.
England Under-15 head coach Justin Cochrane joined Boothroyd in Toulon this year, while Under-20 head coach Paul Simpson was with the Under-21s during Euro 2017.
Southgate and his assistant Steve Holland also travelled to Poland to see Boothroyd and his squad last year.
The England Under-21s are five points clear at the top of Group 4 in their campaign to reach Euro 2019 in Italy and San Marino with four games remaining.
They beat Mexico 2-1 on Saturday to win the Toulon title after previous victories in 2016 and 2017.
