England U21 boss Stuart Pearce has revealed how hooking Danny Welbeck was the making of the Manchester United striker.
He is the only player to have scored so far for the Under 21s in Denmark and will lead the line against the Czech Republic tonight.
But two years ago he was taken off shortly after coming off the bench in a 1-1 qualifying draw with Greece.
Pearce said: "I put him on but, after 20 minutes, he wasn't running around so I substituted him.
"When you do that to any player it hurts. I told him that when you enter the pitch for England you have to work harder than he had for those 20 minutes.
"Credit to him, he took the lesson from that. He's rolled his sleeves up and his work-rate is sensational.
"A lot of the upturn in the Under 21s over the past 15 months or so has been down to him."
