After receiving a late call-up to Fabio Capello's senior squad, he replaced Aston Villa's Ashley Young with nine minutes remaining at Wembley.

"It was a bittersweet moment," he admitted. "I've got love for both countries but I can't play for both.
"I kind of understand that [the boos] but I can't make everyone happy.
"I've been playing for England at every single youth team level so it was a natural progression to move up to the seniors. I am obviously delighted with my progress.
"A couple of friendlies ago I was maybe going to get called up for one of them but unfortunately I got injured," he added on FATV. "So it was just a matter of waiting and getting back fit.
"It was straight to business as I got there late last night and had dinner with the lads. Everyone was very welcoming and I'm just looking to keep pushing on and improving as a player.
"It went pretty quickly tonight to be fair but just to get on the pitch and make my debut, I'm happy. Obviously they scored at the end and it was a good finish from Asa.
