Billy Gilmour

Newly-appointed Chelsea manager Frank Lampard gave Gilmour his senior debut on 10 July 2019, in a pre-season friendly against Bohemians in Dublin. His first appearance in a competitive matchday squad for the first team came in the 2019 UEFA Super Cup against Liverpool, when he was an unused substitute.

He made his under-21 debut in the 2018 Toulon Tournament, in a 1–0 win against France, going on to win the "Revelation of the Tournament" after helping Scotland to a fourth-placed finish.

The next Rangers manager, Pedro Caixinha, described Gilmour as a player with a "bright future" and held talks with the player's family in an attempt to persuade him to stay with the club. Rangers, however, announced in May 2017 that they had reached an agreement for Gilmour to join Chelsea for a "significant fee". Reports suggested that Chelsea would pay an initial development fee of around £500,000, with potential further payments dependent on his progress. SFA Performance Director Malky Mackay had advised Gilmour and his family that he should stay at Rangers, as he would have had more chance of gaining first team experience. Mackay said, "I really hope he goes out on loan quickly to someone and keeps progressing".

Gilmour became officially contracted to Chelsea in July 2017, following his 16th birthday. He joined the club's under-18 squad, making a goalscoring debut in an Under-18 Premier League match against Arsenal during September 2017, and going on to score in each of his first three appearances. In July 2018, after turning 17, Gilmour signed his first professional contract with Chelsea.

Gilmour developed his career as part of Rangers Academy. His progress saw him fast-tracked towards the first team, making his debut for the under-20 development team in December 2016 at the age of 15 and being invited to train with the first team squad the following month by manager Mark Warburton. Gilmour was given a squad number and, following Warburton's departure from the club, was twice included in the provisional squad for Scottish Cup matches by Rangers caretaker manager Graeme Murty.

Gilmour was selected in the Scotland under-16 squad for the 2016 Victory Shield tournament. He made his Scotland under-17 debut against Italy in August 2017, and scored his first international goal in a 2–1 defeat against England two days later.

He made his Premier League debut on 31 August against Sheffield United, coming on in the 84th minute for Tammy Abraham. He made his full debut on 25 September, playing the full 90 minutes in a 7–1 EFL Cup win against Grimsby Town. Gilmour was added to the Chelsea first-team squad on a permanent basis in February 2020. He was widely praised for his performance in a 2–0 win against Liverpool in an FA Cup tie on 3 March.
