Gordon who is a right-sided attacking player full of promise arrived from Derby County in February 2021 for £1.1 million rising to £3.4 million. Gordon quickly caught the eye of Klopp's right-hand man, Pep Lijnders as he explained prior to Gordon making his first-team debut in a 3-0 win at Norwich in the third round of the Carabao Cup on 21 September 2021. “About Kaide, before pre-season we always make sure that our biggest talents start a week earlier than we start,” the Dutch coach told reporters. "They start with the under-23s training and I went to the u-23s training ground to watch and I see one player and he has fire in each moment he touched the ball. He passes players like they are not standing there so I call Jurgen like, “Wow, we have a new player here. We take all these young players to pre-season and you know you have a good player around you is when the senior players start taking care of this young player. When you see James Milner speaking with Kaide. When you see Trent becoming a proper mentor. When you see them invite him to sit on the table. All our boys in our group invited him and it made it, not easier, but good for him to adapt to our team and to our style.” He continued: “What you see a lot with these kind of wingers, they can now play, they can combine. He has a goal in him and he has this natural ability to be in the box between the goalposts to score, even when the cross comes from the other side, and not many talents have that. They have maybe dribbling skills but they don’t have this desire to shoot and come in the box to score. He is a typical Liverpool Football Club winger in my opinion because he has goals, he has speed. We really like him and we’re really happy he’s with us."

Gordon played all ninety minutes of that Norwich game and got more opportunities in January 2022. He appeared against Shrewsbury in the FA Cup, scoring in a 4-1 win and then made his Premier League debut, coming off the bench against Brentford at Anfield. He also started the League Cup semi final at Arsenal. However the following month he developed  pelvic problem linked to his growth which kept him out of action for the reminder of the season. The club were patient with his recovery and although he went on a pre season training camp, it was to bond with the players rather than appear in friendlies. Gordon remained out of action for the whole of 2022/23 but when pre season training began for the following campaign coaches expressed hope that he would soon be fully involved. He was used sparingly in the first few weeks, but went on to start all Premier League 2 games from January onwards. He also made his first start for the first team, away to Union SG in the Europa League group stage. A season long loan deal was agreed with Championship side Norwich City for 2024/25, but this was terminated mutually by both clubs in January as he was restricted to just ten appearances. On transfer deadline day in January 2025, a loan deal was agreed for Gordon to spend the remainder of the season at Portsmouth. However, it was another frustrating spell with all of his five appearances being as a substitute.
