Emma Raducanu smiles as she dons a chunky blue sweater and jeans for casual ...

British tennis sensation Emma Raducanu appeared to be having a business meeting on-the-move on Monday.

The US Open 2021 champ, 18, flashed a smile as she was snapped taking a stroll in London alongside her sports agent Chris Helliar.

Emma donned a blue roll-neck sweater in a chunky design, despite the clement September weather.

She added slim stonewashed jeans and white trainers to the look, perching a pair of vintage shades on her head.

She wore her raven locks sleekly around her shoulders and displayed a creamy visage of natural make-up.

She tied back her mane later on as she and Chris strolled along, both checking their phones - which are bound to be popping given the events of the past week.

The tennis sensation made sporting history by winning the US Open earlier this month - the first British woman to win a major title for 44 years since Virginia Wade lifted the Wimbledon trophy in 1977.

She is also the first qualifier in history to lift a grand slam.

The teenager has been heralded as a 'sponsor's dream', and is on course to becoming the highest earning female sports star of all time.

It was also reported that she laid the groundwork for her potential earnings aged 17, registering Harbour 6 Limited to manage her finances. 

Her return home to the UK comes after a whirlwind week following her incredible triumph in New York. 

Emma told reporters outside her home: 'It's a great feeling to be home. I've been away for seven weeks so it's nice to be back. It was nice [to hug her parents]. Nice to see them again.'

The smiling tennis star also said she was looking forward to relaxing but hasn't thought about any parties or reunions with friends.

She said: 'I haven't thought of anything [going forward]. I'm just enjoying it and relaxing and recovering. We will make some plans.'
