The courage required to make a new start has paid off. Bompastor has won as many trophies - three - as she has suffered defeats this season.

This summer, she will not have to navigate a move to a new country. She won't have to relocate her four children all under the age of 10. Which raises the question: what could she go on to achieve next season without those hurdles to overcome?

'We moved as a family, with our four kids,' Bompastor explained. 'It was tough for them to move from their own country. Some things were easy, and some things were more challenging.

'For them, it's a new place and a new language. I think they are still slightly struggling with that, but they were at an age when it was still possible to do it.

'We had to be brave because it’s not easy, even when moving alone.'

Many would've forgiven Bompastor for making a slow start to life in her new role. She says herself that she had big shoes to fill in replacing Chelsea's legendary manager Emma Hayes.

There was no slow start, though. Her first match was a 1-0 win against Aston Villa. Then, we beat Crystal Palace 7-0. Wins over Real Madrid and Arsenal came next. Bompastor was not beaten until we faced Manchester City in the first leg of the Champions League quarter-final in March.

'Overall, the adaptation has been great,' she continued. 'The club helped us settle in well, and that's what made the difference. We felt like part of the family from the beginning.

'From the moment we joined Chelsea, we felt special. We put everything into our work and anytime we needed support with the family – with anything in fact – the club helped us.

'That was so important because I believe if you feel well in your head away from the pitch, you give your best on the pitch. That’s been part of our success this season.

'The fact the kids are happy brings me the happiness I need to enjoy my everyday work. I’m so pleased we are offering our kids the opportunity to learn a new language and settle into a new life, which will help them in future.'

Bompastor and her family have embraced life in London over the past year.

Here, she feels like she belongs. Acceptance is a value the coach appreciates, and one she's found in England.

'London is such a nice city to live in,' she smiles. 'We appreciate being at the club and life here is great.

'I appreciate the open-mindedness and the diversity in London. You can feel it when you are just walking in the streets, no one is going to mention anything to you about how you are dressed or if your hair isn’t perfect.

'People live their lives, accepting our differences and this mindset is a perfect education for my kids. I want them to be open-minded and accepting of every difference in life. For this reason, London is the best place to be.'

With a domestic Treble already in the bag, Bompastor has already proved she is a ruthless winner.

Yet, she does not achieve excellence through a heavy-handed approach. Her values are people-centric and highlight how those strong bonds translate to a feeling of shared pride and loyalty on the pitch.

'When I first arrived, we spoke about ambition,' the coach explained. 'On the pitch, I wanted to make sure everyone was on the same page. My job as a leader is to make sure I give clarity around the goals we have together.

'I also had to make sure they understood the environment I wanted to work in. They needed to feel that from the beginning. I wanted to create a family environment because, you spend so much time together, sometimes more time with your staff and players than with your whole family.

'Players need to feel safe, and passionate about their work in this building. Everyone must be able to express themselves. That’s vital for me in terms of values as a human being.'

'I could feel the ambition when I first met the sporting directors, the owners, the players and everyone at this club. They’d had so much success before I joined.

'For me, it was a case of making sure I maintained those ambitions and that winning mentality. Maybe having a new manager felt like a refresh for some players and the staff because Emma had been the manager for 12 years and sometimes it’s good to have change and bring in a new era.

'She had done such a good job with the team and the players. Considering it was my first year here, I think it was a good season.'

After winning three domestic trophies following her big move from France, it is fair to say that is an understatement.
