Mourinho was brought in to replace Mauricio Pochettino in November last year, with Tottenham 14th on the Premier League table but the Portuguese manager engineered a sixth place finish for the Lilywhites, qualifying for the Europa League in the process.
Tottenham have made a strong start to the 2020/2021 season and are currently top of the table on goal difference ahead of champions Liverpool.
Tottenham head into Sunday’s North London derby against Arsenal with the longest unbeaten run in the division, last losing on the opening weekend of the season against Everton.
"I think there were a lot of questions asked when Pochettino was sacked when he was," Robinson told Stats Perform News.
"Eyebrows were raised when Mourinho came in, but I think Daniel Levy has to take a lot of credit.
"He's employed a world-class manager, a winner of a manager, someone who knows how to win trophies, a certain mentality that's needed in the dressing room.
"Jose was brought to Spurs for a reason. Pochettino took them so far but couldn't get them over the line.
"He [Mourinho] has got that mentality, that cutting edge, he's not afraid to make big decisions and he's been heavily backed in the transfer market again by the chairman, which was fantastic to see.
"You look at the squad they've got now, they've got a real serious chance of winning the title this year."
