First of all, Spurs wanted an interim head coach until the end of the season. And that immediately narrows the field down.
Within that, the Spurs hierarchy were looking for someone with top level managerial experience who plays attacking football.
After reviewing their options, it is understood Spurs felt Tudor fit the bill for a few key reasons.
He has experience of working at some top European clubs – and managing big name players.
Tudor's reputation is for aggressive football with an attacking intent. This element was particularly important to Spurs after criticism of their style of play under Frank.
Tottenham are also said to have admired his work improving teams on a short-term basis.
For example, his Lazio team were unbeaten in the league for his first two months after he joined.
At Juventus, he lost only one of his first nine games. In his first full season, he was unbeaten for his first eight matches. His downfall came quickly, however, following that run after losing three away games in a week – to Real Madrid, Lazio and Como.
Tudor will be an interim manager and it is thought that they will be looking to secure a different, long-term option in the summer.
However, like with Michael Carrick at Manchester United, it may well be an intriguing conundrum if he hits the ground running and sustains a good run of form through what is left of the season.
