Chelsea boss Frank Lampard was pleased with Billy Gilmour's cameo for their FA Cup win at Hull City.
Michy Batshuayi and Fikayo Tomori struck for Chelsea in the 2-1 win.
On Gilmour, Lampard enthused: "I thought Billy Gilmour was the best player on the pitch for the period of time he was on the pitch.
"He came in, he passed it, he moved it, he played the simple pass through the lines, he had little bits of contact.
"I trust him to come on and do the job."
