It was a bittersweet night for the teenager who shone on his second start of the season but was then dismissed seven minutes from time after picking up the second of yellow cards - the second for a pull-back on Marten De Roon.
“We knew he could do it. We thought it would be a game we could have the opportunity to run. Phil has quality to make box to box, with his speed," the City boss added.
“He is still young, with a lot to improve.
“He played so good. Every minute is more experience for his future. He played a high level.
“The way he played, (he is an) incredible player. He will know after one yellow card the need to be more careful.
“He is absolutely not going to be fined (for the red card). We have to pay him for the way he played!”
