The Cardiff midfielder signed a season-long loan with Leeds United.
A product of the Norwich City academy, the 23-year-old becomes the fifth signing of Leeds United’s summer, following Charlie Horton, Lee Erwn, Chris Wood and Sol Bamba.
An energetic midfielder, Adeyemi arrives as a replacement for Rudy Austin, who left Elland Road at the end of last season when his contract expired. He has a wealth of Football League experience, and has played under head coach Uwe Rosler before - when he moved on loan to Brentford in 2012.
He may be young and yet to reach his potential, but he is a proven quantity in the Championship, and brings competition and cover to a midfield already well stocked - with the likes of Luke Murphy, Lewis Cook and Alex Mowatt all established stars at Elland Road.
It was a signing which came out of nowhere, but on the surface there are many reasons why Rosler has targeted Adeyemi. He fills a role in the team absent since Austin's departure, and following the completion of the deal, Leeds fans took to Twitter to express their pleasure at the loan signing.
I've got a good feeling about Adeyemi and this squad as a whole. Youthful but quality prospects not just untested kids. #LUFC— KaiserChief82 (@KaiserChief82) July 14, 2015
The new leeds signing, Adeyemi, looks an ideal replacement of strength and power in place of Ruddy Austin. Shame it's only on loan #lufc— Alexander Vautrey (@a_vautrey) July 14, 2015
Brilliant news about the signing of Tom Adeyemi onwards and upwards for Leeds now #lufc— Adam Bush (@adzybush) July 14, 2015
Reading good things about Adeyemi signing, sounds like a player we need. Round pegs in round holes for once maybe at #lufc ?— Ross Norman (@rossi_norm) July 14, 2015
Adeyemi seems like a great signing. More positive business this week. Once again, through gritted teeth, Cellino deserves some credit #lufc— White Answers (@whiteanswers) July 14, 2015
204 passes with 94% being 'forward passes'; sounds like Adeyemi will fit Rosler's ideology well. #lufc— Ryan Nicholson (@xRyanMOT) July 14, 2015
