With the Blues already through to the last-16 as group winners, Lampard was able to heavily rotate his side for their final fixture, at Stamford Bridge.
That saw Gilmour, whose breakthrough last season was one of the great successes of Lampard’s first year in charge, handed his first start of the campaign on his return from a four-month layoff with a knee injury.
“I thought Billy was outstanding on his return, I felt very comfortable with him coming back in, he’s trained so well, done his rehab and he deserved his chance tonight,” said Lampard.
With the likes of N’Golo Kante, Mateo Kovacic and Mason Mount in superb form, and Tuesday night’s goalscorer Jorginho also waiting in the wings, there have been suggestions that Gilmour may be loaned out when the transfer window opens next month in order to give him more regular playing time.
However, Lampard added: ”The way he played today and how he trains I see him growing with us, he’s going to be a Chelsea player, [it’s] just making sure the pathway is right for him.”
