Mauricio Pochettino’s men have not added to their ranks since last year January transfer window, with the decision being criticised.
Tottenham are yet to win a trophy since 2008 [League Cup] and the 38-year-old has advised the Lilywhites to recruit the ‘world-class’ player so as to boost their chances of halting their title drought.
“Maybe the only way they are going to get better is with a genuine world-class player,” Hargreaves said on BT Sport.
“He [Pochettino] only wants a player of high character. I think he wants people to fit in and not upset the balance.
“I would like to see Zaha at Tottenham.”
This season the Cote d'Ivoire international has scored four goals and created two assists amid several dazzling displays.
