Osman's selection has earned comparisons with that of Tottenham midfielder Scott Parker, who four-and-a-half years after winning his third cap, was handed a fourth in February 2011 and went on to become an integral figure in Fabio Capello's Euro 2012 squad.
"Scott broke into the squad really early," said Osman.
"When he got back in later on he was a lot more experienced and mature football-wise and was able to show that on the pitch.
"I seem to have developed late in the game as well.
"I didn't make my debut until I was 21 and didn't stay in the first team until I was 23, so to make a late arrival here doesn't actually surprise me."
