The highly-rated defender who did so well in our first two Barclays Premiership games against Liverpool and Newcastle put pen to paper at Spurs Lodge last week.
"Phil is one of the big prospects in England as a right full-back," said Head Coach Martin of the player who has played for England at Under-16, 17, 18, 19 and 20 levels.
"Normally when players are 18 they play like a young player but I like him because he's 18 years of age, yet he's a mature player.
"He did a teriffic job in the first two games of the season and he has a bright future."
Martin suggested it was vital Phil came through those first two games of the season, not least performing without nerves or fear in front of over 50,000 at St James Park.
"Yes, it was the most important thing for him," added Martin. "It was a big step forward.
"If he hadn't played well, people would have doubted him but now everyone knows he is a good player.
"Phil is also one of the players who identifies with the club because he came through the system at Tottenham and that is important.
"We hope there are more players like him coming through who know what the club is all about."
Martin Jol is delighted that Phil Ifil has has been rewarded for his great progress with his first professional contract at the club.
