He put up a brave fight against world number three Roger Federer during his Wimbledon fairytale.

But during an appearance on ITV's This Morning, on Thursday alongside his stunning girlfriend Jenny Bate, Marcus Willis revealed he suffered from low self-esteem when he was younger.

The tennis player told hosts Holly Willoughby and Phillip Schofield: 'I lost my way between 19-24. I worked, but I didn't work 100 per cent, I looked in the mirror and thought, "You're a bit of a loser".’

His prize money for reaching the second round of the main draw at the iconic grass court tournament is a cool £50,000.

However, the 25-year-old remained grounded when asked about the large sum. He said: 'I haven't really thought about the money yet, it's a bit of an added bonus.'

Marcus, who coaches tennis at Warwick Boat Club, added he will return to the town tonight to do some coaching and training.

He was the lowest-ranked qualifier to reach the second round at a Grand Slam since the 1988 US Open.

Ranked number 772 in the world, Marcus experienced a dream come true when he beat Lithuanian Ricardas Berankis on No 17 Court on Monday, securing his match against Federer.

Back in the studio, the sportsman wore his tennis white in the studio as well as a pair of blue Nike kicks and a lightweight jacket.

He was joined by his glamorous dental surgeon girlfriend Jennifer Bate, 30, who looked chic in skinny black jeans and tiny strappy nude heels.

She completed the outfit with a puffy nude jacket and a striped top. The blonde beauty wore a slick of bold lipstick and a touch of colour on her cheeks for a warm finish.

The mother-of-two was in fact the reason her beau was on the court as at the start of this year. He was ready to turn his back on the dream and move to America to become a coach.

But in February he met the NHS dentist, from Warwickshire, at an Ellie Goulding concert and the blonde beauty eventually convinced him to stay.

Speaking after his match with Federer, Marcus said: 'I had options in Philadelphia. Nothing was dead set. But, yeah, it was an option I had. Don’t know if I would have gone or not. But, yeah, I met the girl. She told me not to, so I didn’t. Do what I’m told.'

Jennifer coyly admitted there was an “instant attraction” when the pair met, as she revealed: 't’s been quite intense, travelling and watching matches, but we’re crazy about each other.'

Of stopping his America move, she said: 'A week after I met him he said he was going to America and he’d given up on tennis. My brother loves tennis and said to me "this guy is a big deal" and so I told him we believed in him, give it a shot, it’s worth it – and he did. He wants it so much and has worked really hard for this.'

In 2010, aged 24, Jennifer took part in the 'Miss Professional' beauty contest where she competed against some 12 other girls in a bid to compete in the Miss England finals.

The talented stunner also won the title 'Miss Charity'. The dental profession runs in her family - both her father and brother are thought to be dentists and her mother a dental hygienist.

The beautiful blonde joked she is a 'cougar' after his first round win at Wimbledon.

She was only able to make it to the match after the suction machine at work broke, but once at the Championships she was fully involved with the match, even taking off her shoe at one point to join in when supporters chanted 'Shoes off if you love Willis'.

She said: 'I wasn't even going to be here. The suction just stopped working and usually you just unblock it and you carry on. I was not expecting this, that was incredible tennis.'
