HQNetflix has just released a three-part documentary series on the Portuguese manager José Mourinho, just as he has made his return to Real Madrid 13 years later. However, Mourinho said he "needed to feel loved" after a tough final year at Real Madrid, and chose to return to Chelsea instead. Mourinho ended up at Manchester United in 2016, winning the Europa League, but was also sacked after two and a half years. But the most talked-about part of the documentary in Spain is when he talks about Iker Casillas, who was captain of the team and considered the best goalkeeper in the world at the time when Mourinho took over the team. 13 years later, Mourinho may face similar problems of major stars and major egos in the dressing room, will he be able to get better results this time?
