Tranmere have signed midfielder Harvey Gilmour on loan from Sheffield United until January 2019.
The 19-year old has been with Rovers since the start of the week and came on as a substitute in Tuesday night's friendly against Liverpool.
Manager Micky Mellon said: “I'm pleased to add Harvey to the squad.
“He's a talented young player who will increase the competition for places in midfield and he put in a good performance on Tuesday night.
“He's got a great attitude and wants to improve as a player and I'm sure he'll do that here.”
