Tottenham Hotspur sold the youngster earlier this summer.
The youngster’s career to date has certainly been an interesting one, with Tottenham signing him off the back of a very impressive under-17 World Cup in which he starred alongside Manchester City’s Kelechi Iheanacho and ultimately lifted the trophy.
Despite that deal, Yahaya remained somewhat elusive until it was confirmed last month that the 18-year-old attacking midfielder had signed for Portuguese side Portimonense, with his agent confirming in an interview with Desporto Ao Minuto that Spurs had received £650,000 for him.
At first glance it was not bad business for someone who never actually turned out for the North London club, but according to Garba, Tottenham will rue their missed opportunity in the long run.
Speaking to Own Goal Nigeria, he said, “I was shocked when they (Spurs) decided to sell him, you can’t let a young talented player leave just like that.
“He has all it takes to succeed in England, pace, power and finishing; they will definitely regret letting him leave.”
Garba went on to say that he thought Yahaya will one day return to England a better player than when he left, but for now it remains to be seen if Tottenham made the right call.
