We can’t believe we’re about to say this after spending so much in the summer on new additions, but Leeds United have a centre-back problem.

Indeed, Liam Cooper and Diego Llorente have had injury problems as of late, while another injury to Kalvin Phillips will see Pascal Struijk taken away from his centre-back duty in order to play in a midfield role.

United need more options in that position, and luckily they have a young defender waiting in the wings who could fill that void perfectly.

Oliver Casey has had a small taste of first-team football at Leeds, impressing in his debut against Huddersfield Town last season, earning a number of plaudits from fans, but now it may be time for him to get more opportunities in the starting XI.

There’s no doubting that Casey has the talent to go a long way at Leeds.

Indeed, the defender received a glowing review from Danny Mills over the summer, and the former United star’s words on the 20-year-old should have every Leeds fan excited.

“He looked very much in the mould of Ben White in all honesty," Mills said.

“When he came on, he looked calm, he looked assured and composed when he needed to be coming out from the back.

“And for a young player, he looks a really good prospect.”

We don’t need to tell you why Casey being in the mould of Ben White is a good thing, the Brighton man was a star under Bielsa last season. He started every single league game and won the club’s Young Player of the Year award.

It’s not just Mills who thinks highly of Casey either, with Carlos Corberan speaking highly of him before his departure to Huddersfield town over the summer.

“Olly’s a fantastic guy and a guy you enjoy coaching. He’s very focused and he’s very clear about his target of being a football player — but with an open mind about receiving the information he needs,” Corberan said.

This all sounds incredibly positive with Casey being a talented player who is open to learning new things and with Bielsa’s track record of improving players, it shouldn’t be a tough task to mould this 6 ft 2 centre-half into a Premier League level defender.
