Luke Ayling says his Leeds United teammate Kalvin Phillips has 'everything'.
The 25-year-old midfielder has transitioned seamlessly into the top-flight this season, ensuring his inclusion in Gareth Southgate's England plans.
And Ayling says Phillips has 'slimmed down' since Marcelo Bielsa's arrival at the club.
"He can dive into a few tackles, can't he," said Ayling. "When I first come five years ago, Kalvin was a number ten and a bit of a number eight. Box to box.
"And the first day the gaffa come in he told Kalvin 'no, you are going to be a number four. You are going to get on the ball and play'.
"Straightaway, he took to it and he has now grown into it. He has slimmed down a little bit and he can cover good ground. He can pass the ball short, he can go long and find a pass, so he has everything."
