Defoe hit the post in the second-half of the 1-0 win.
“It’s always nice to play for your country and I was delighted to get on," he told The Sun. “When I got that shot off, I thought it was in but it hit the post.
“Hopefully, when I get over to the Euros, that one will go in.
“This squad is probably a better mix than the one which went to South Africa.
“A lot of the younger lads have come through, which is really good to be honest — they really have a lot of energy. After the season ended we all had a little rest — about 10 days off — so I think that helped as well.
“There is always going to be pressure, not only in championships but in the games in general. We’re a great footballing nation and we’ve got great players.
“It’s important for the players to just enjoy it. This is why you play football — to play for your country and to play in major tournaments. The manager has said to us, ‘Go there and just enjoy it and do the country proud’.
“There’s a really good feeling representing your country at a major tournament. Having played the one before, having experienced it, I just want it again.
“Hopefully, this time around, we get off to a good start and we do well because I think everyone deserves it.”
