Demarai Gray fired England U21s to Euro 2017 as they sealed a 1-0 victory in Kazakhstan.
The Leicester winger scored his first goal for the U21s as they made light work of boss Gareth Southgate's absence to win Group 9 with a game to spare and qualify for the tournament in Poland next summer.
U20 boss Aidy Boothroyd took over with Southgate in interim charge of the senior squad following Sam Allardyce's exit after the Daily Telegraph's investigation into corruption in football.
He handed debuts to Newcastle goalkeeper Freddie Woodman and Everton defenders Brendan Galloway and Mason Holgate in Aktobe and England made a lightening start to grab the winner after six minutes.
A snappy flowing move started with James Ward-Prowse and Ruben Loftus-Cheek swapping passes before Ward-Prowse sent Nathan Redmond scampering down the right.
The Southampton forward moved into space and crossed low for the onrushing Gray who escaped the hosts' defence to tap in from seven yards.
England host Bosnia on Tuesday at Walsall in their final game aiming to go through the group unbeaten after five wins and two draws from their seven games so far.
