Three-time Premier League title victor Mourinho was appointed by Tottenham on Wednesday, less than 12 hours on from Mauricio Pochettino's departure.
RMC report that Premier League side Tottenham Hotspur had been courting Lille's two now ex-members of their technical staff, João Sacramento and Nuno Santos, for weeks, informing the LOSC board of their intention to move to Mourinho's new club last month.
Tottenham once again get a mention and the report explains the Premier League club have "gone well beyond a few surveys" when it comes to signing the player. The first one was from (United managing director) Richard Arnold. We have good memories with him and I played many times against him.
Even after opening his first comments as Tottenham manager by praising his predecessor Mauricio Pochettino, Mourinho couldn't resist a one-liner that reminded everyone - however unintentionally - that Tottenham had replaced a coach who never landed a title with a serial trophy victor.
By the time he was sacked by Manchester United in December 2018, it became clear Mourinho's relationship with the players had fractured.
"You never lose your DNA".
"Yes, I think we will get on well", he added. But I realise during my career I made mistakes but I won't make the same mistakes.
"Everything will be fine for him, but it was a big one, when I first heard I couldn't believe it".
Azpilicueta played under Mourinho for just over two years at Chelsea during the manager's second spell at Stamford Bridge, and was part of Mourinho's title winning team in 2014/15.
Mourinho will take charge of Tottenham for the first time on Saturday when they travel to London rivals West Ham.
Tottenham hasn't won the league since 1961.
