Tommi O'Reilly, who is 21 years old, previously spent half of last season with Shrewsbury Town in League One. He then moved to MK Dons in League Two for the second half of the season.
During his time with the two teams, O'Reilly made a total of 34 appearances and gained valuable experience.
As a product of the Aston Villa academy, O'Reilly has already played in senior matches, including the Europa Conference League.
With his experience and skills, O'Reilly is expected to make a positive contribution to Crewe Alexandra's team.
The season-long loan will give O'Reilly the opportunity to play with a new team, gain more experience, and develop his skills further.
It's exciting to see how O'Reilly will perform with Crewe Alexandra, and fans are looking forward to seeing him in action.
