Waller has already had several loan spells in the past, including with Rochdale in the National League. He has also played for Lancaster City and Hyde United.
At Crewe, Waller will compete with Tom Booth for a spot in the starting lineup. This will be an exciting opportunity for him to prove himself and take on new challenges.
It's worth noting that Waller is still under contract with Burnley until 2026, with an option for an additional year. This suggests that the club is investing in his development and sees him as a potential future asset.
