BURY boxer Scott Quigg returns to the ring on Saturday night at Wembley Stadium believing he is in the best shape of his career.

The 28-year-old takes on Romanian Viorel Simion in front of 90,000 fight fans on the undercard of the heavyweight showdown between Anthony Joshua and Wladimir Klitschko in his second fight at featherweight and first under new trainer Freddie Roach.

And he is confident fans will see his improvement working with Amir Khan's former coach in America first hand under the Wembley arch.

"I would go as far as to say it is the best I have ever prepared," Quigg told Bury Times.

"I feel a lot stronger and happier in myself and comfortable after going up a weight.

"Moving to America was the best decision I could have made – I needed to freshen things up a bit.

"It has been the change of environment I needed.

"I had some great times with Joe [Gallagher] – he is the best trainer in the UK and one of the best in the world.

"But I thought a change would help me take things to another level again.

"I am learning every day with Freddie.

"I always went out to America every year and gradually built a friendship with Freddie’s camp.

"I asked him if he would be interested in training me and when he said yes it was a no-brainer for me.

"In boxing you have to be selfish and look after number one.

"I am in a great place at the minute and learning new things every day.

"The knowledge Freddie has is amazing and it is helping me a lot listening to him.

"The sparring is excellent as well. I have been working with the quality of fighters like Oscar Valdez, who is the current WBO featherweight champion.

"Going toe-to-toe with that calibre of boxer gives you confidence as well."

Quigg is confident of success on Saturday night in a bout which is now an eliminator to fight IBF world featherweight champion Lee Selby.

But he knows he will have to be at his best against Simion – a man who has lost just once in his 22-fight professional career.

The Bury star said: "Viorel Simion is a tough opponent but it is a fight that excites me.

"He is aggressive and resilient and was a very good amateur.

"He has only lost once and that was on points to Lee Selby in 2013.

"This a big chance for him on a big stage as well so he will be up for it.

"I know for my second fight at featherweight, it will be a test but I am massively confident.

"Wembley is going to be a huge night for me to be in front of such a big crowd.

"I am grateful to Matchroom, Anthony Joshua and Wladimir Klitschko for allowing me to be on their bill.

"It is a big night for me – not only fighting at Wembley Stadium but it is also my first fight under Freddie.

"It is a chance to show what I have learnt and my improvement and I am so determined to do that."
