Rio Ferdinand has praised his wife Kate's homeschooling skills during lockdown as he admitted his kids find him a "stern teacher".

The former England footballer told how he is a "three out of 10" as a teacher due to his "lack of patience" but gives Kate a "nine out of 10".

He also admitted as he discussed the new football-themed Numbers Game on the online education platform, Twinkl that his children think he's 'hard' and even 'grumpy'.

The Man United legend, 42, applauded Kate as he showed his appreciation for teachers across the UK, saying: "I have so much respect for what teachers do. It's a hard job.

"The thing I've noticed is how intense it can be and how the teachers manage it all day and the pressures of managing all these different kids who have different ideas with the ways they want to learn.

The former England footballer, 42, told how he is a "three out of 10 as a teacher" to the couple's children Tate, 12, Lorenz, 14, and Tia

"But one of the biggest things we've learnt to respect from teachers is their patience to deal with the kids.

"As a teacher I'm a three out of 10 because of my lack of patience. But Kate - I give her nine out of 10."

Rio said his homeschooling technique for his kids - Tate, 12, Lorenz, 14, and Tia, nine - is inspired by his old manager at Man United Sir Alex Ferguson.

The dad says he is a strict disciplinarian who isn’t afraid to put his foot down if his ‘students’ step out of line during 'class'.

He said: "I think I've learned a lot from Sir Alex Ferguson. I've not gone for the soft touch approach.

"It's important to be disciplined with them during the school day, keeping on top of them.

"These are my own kids and I love them, but they can be difficult. You have to give them a bit of leeway but it's important to follow the fine line.

"We were having dinner and Kate said, "tell your dad what you told me the other day". They didn't want to so Kate said, "sometimes you're quite stern, hard and sometimes even grumpy"."

Rio also praised football for improving his number skills as he discussed The Numbers Game, an interactive maths football game for children aged between five-14.

He said combining the two can be a 'really good way of learning'.

Rio shares children Lorenz, Tate, and Tia with his late wife Rebecca Ellison who passed away in 2015 following a battle with breast cancer.
