The youngster looks set to add to the growing list of academy graduates turned first-team players at Elland Road.
The 19-year old made his first start of the season – and third senior start in total - in Saturday’s goalless draw with Reading, and Rosler was thoroughly impressed by his contribution.
“Kal coped very well in my opinion throughout the (Reading) game. He raised himself up to the level, to the tempo, to the intensity.”
“He is earning my trust by giving me performances like he did against Reading because I felt I can trust him, I can play him and he will not let himself, or the team or myself down.”
Thorp Arch has seen an abundance of talent make the breakthrough in recent years with the likes of Sam Byram and Alex Mowatt amongst the highest-rated young players in the country, and early indications are that Phillips will soon sit comfortably in that bracket.
The classy midfielder never looked overawed by the occasion and was a composed figure in what proved to be a close encounter, but Rosler remains keen to introduce him to the first-team picture carefully.
“There are certain periods where we can allow players who don’t have a lot of experience to throw them in and see how they cope… but when everybody is fit I don’t think Kal will play week-in, week-out.”
It’s a sensible approach from the German but given the success of the club’s last few academy graduates, it would not be a surprise to see Phillips become a regular before too long.
The prospect of the Whites fielding an all academy midfield trio of Alex Mowatt, Kalvin Phillips and Lewis Cook is a distinct possibility in the near future, and speaks volumes for the work being done at one of the country’s top academies.
