"At this level every game is difficult," the Tottenham striker said.
"They will make it hard and sit behind the ball and try to frustrate us.
" I have played in a number of games against the so-called smaller countries and it's difficult to get the first goal.
"It will be a difficult game, when we get the first goal we can go and get the second."
"I have been playing the lone striker for my club and I have enjoyed it," Defoe said. "To be honest playing with good players it is not really a problem if people get close.
"It we get to control the game in midfield when we get a chance we have to take it."
