Bartel only celebrated her 20th birthday last month yet she doesn’t look remotely phased by her new surroundings. And why should the midfielder given she has achieved so much in her short career, with honours at both international and club level.

‘I am a very ambitious person, so I’m all about winning, winning, winning,' Bartel insists. 'So I think I’ll fit in at Chelsea - I know what is expected from a player who plays for this club.

‘My short-term goal is to learn here, keep improving and make the most of being surrounded by amazing players. My long-term goal is to win everything I can possibly win here at Chelsea.’

Given her drive and determination, Bartel should quickly feel at home among a squad that has just won a fifth consecutive Women’s Super League title.

A graduate of Barcelona's renowned La Masia academy, Bartel also appreciates her next challenge of adjusting to English football is a big one.

‘I’m very happy to be in London and here at Chelsea,’ she adds. ‘I think it was a hugely important decision but this is the best club and the best next step for my career.

‘I have watched a lot of games from the WSL in the last few years and I think it is probably the strongest league at the moment in women’s football. So I am very happy to have the opportunity to play here.

‘I’m very excited about moving to another country, living on my own, and having the chance to play for a club as big as Chelsea.’

A technically gifted midfielder, with an eye for goal, the Spaniard is a high-quality addition to the ranks. And Bartel is not only our first signing of the summer but the first of a new era following Sonia Bompastor’s arrival as manager.

‘I'm really looking forward to playing in this new team with Sonia Bompastor. I know that she's a fantastic coach. She has already won championships both as a player and as a manager. So I think this will be good, both for me and for the team.’

Despite her age, don’t expect Bartel to be a signing for tomorrow rather than today. Youth has never been a barrier on her journey to England.

She made her first team debut for Barcelona against Eibar in 2021 aged 17 years and one month. In the process, Bartel became the fourth-youngest player to feature for the Catalan club.

That is no mean feat considering Barcelona’s strength in depth over recent seasons. And Bartel believes she has hugely benefited from developing in such a competitive environment.

‘I'm very grateful for my time with Barcelona and every moment in the academy. They pay a lot of attention to minor details and are able to really develop players.

‘Working every day in La Masia with the players and learning with staff brought a new challenge every day. So over the years, everything I have learned is something I can take forward and use now I am here at Chelsea.’

Signing with the Spanish champions from Espanyol when she was only 15, Bartel’s development in Catalonia also allowed her to learn up close from one of the best players in the world.

‘My idol in football is Aitana Bonmati from Barcelona,’ she reveals. ‘So I am very grateful that I could spend so much time in Barcelona training with her, learning certain things from her.

‘Aitana would be the player who has influenced [my game] the most so far.’

Last season, Bartel featured regularly for Barcelona’s successful B team – and saved her best for the final day.

With her side needing to win to confirm the Primera Federacion title, she scored twice in a 5-0 victory over former club Espanyol to seal silverware.

A year ago Bartel was also part of the Spain side that won the Under-19 European Championship. Yet the best moment of her football career so far came elsewhere on the international stage.

‘If I had to pick one moment (as a highlight) it would be the under-20s World Cup final with Spain. That was a hugely special moment and one I will always cherish.’

Bartel played the full 90 minutes as La Roja beat Japan 3-1 in Costa Rica to lift the trophy. She was already a world champion.

Further proof that whether pulling on the shirt for club or country, her winning mentality doesn't shift. Next in her sights is making her mark on English football.

And even in the middle of the off-season, the sight of the Stamford Bridge pitch is enough to get Bartel excited over the prospect of her home debut.

‘That first game at home will be a day I’m looking forward to the most. I know I'll be very happy to get on the pitch – whether here at Stamford Bridge or Kingsmeadow – and show all the fans what I can do. I’ll be happy to play for this club anywhere.’
