The Icelandic international — Emil made his full debut as a substitute against Italy last season — has scored twice in four Spurs XI friendlies so far.
Playing wide on the left, the 21-year-old’s ability to whip dangerous crosses in from that flank has caught the eye.
Coach Clive said: “Emil is getting into the positions you’d hope from a wide left player and did particularly well with his goal against Cambridge City because it was a move down the right and he timed his run perfectly to get on the end of it.
“We’ve worked on that in training and he’s taken it on board.
“He’s improved with each game, he’s getting more opportunities and has taken his goals well. He’s beginning to learn that role and has been a threat.
“When he’s wide he’s in positions where we can find him with the ball and with the quality he has, he can provide ammunition for the front boys as well as getting onto crosses from the other side, just like he did at Cambridge City. I’m pleased with him so far.”
Clive Allen has been pleased with what he’s seen so far of Emil Hallfredsson in pre-season.
