Only recently turned 17, Alex joins us from Norwegian second division side SK Gjovik Lyn.
Sporting Director Damien Comolli said: “Alex is a talented player, very, very quick and has an impressive goalscoring record in what is his first season in the first team at Gjovik Lyn.
“He came here for a week’s trial and impressed both our Academy and senior staff and we are delighted to sign him for our Academy and development squads.
“Alex had offers from many top clubs both in England and across Europe but he showed a real desire to play for Spurs.”
We are delighted to announce that we have agreed terms to sign young Norwegian striker Dag Alexander Olsen, subject to a medical.
