Former Tottenham manager believes that his former club could end up regretting having not signed Aston Villa midfielder Jack Grealish as he could have gone on to be a star for the team.
The attacking midfielder was one of the players whom Mauricio Pochettino had hoped to sign during the summer transfer window.
During the early parts of the transfer window, it looked as if a deal was likely to go ahead as Villa were struggling financially.
However, their financial problems were solved after the club had been bought by new investors and this led to them hardening their stance on a possible sale for Grealish.
