11 players who have played for both.
Leeds United are back in Sky Bet Championship action on Saturday (12:30pm), taking on Sheffield United, looking for a fourth win on the bounce.
Ahead of the clash at Elland Road, we look at 11 players who have played for both Yorkshire sides.
The goalkeeper played under Neil Warnock at Bury, Sheffield United, Queens Park Rangers and Leeds United. He played over 250 times for the Blades from 2002-2010 and was at Leeds from 2012-2014.
Bromby is one of the few players to have played for both Sheffield Wednesday and Sheffield United. He had two spells at Bramall Lane prior to joining Leeds in 2009 and he helped the Whites win promotion to the Championship from League One.
The defender broke into the first team at Leeds, prior to moving to Sheffield United in 2007. Kilgallon is still playing in Scotland for Hamilton Academical, after recently moving from fellow Yorkshire rivals Bradford City.
Now at fellow Championship side West Bromwich Albion, Bartley spent time on loan with the Blades whilst at Arsenal. He spent the 2016/17 season at Leeds, enjoying a successful loan spell from Swansea City.
Speed is remembered fondly by every club he played at. He helped Leeds win the First Division title in 1992 and ended his career with the Blades, where he was from 2008-2010.
Brown joined Sheffield United on loan from Manchester City, before the move was made permanent. After spells at Tottenham Hotspur, Fulham, Wigan Athletic and Portsmouth, Brown joined Leeds.
Officially named Sheffield United’s greatest ever player, Currie was at Bramall Lane from 1968-1976, playing over 300 games for the club. He moved to Leeds from the Blades and went on to play over 100 games for the Whites.
The forward joined Leeds from Sheffield United in 1967. He scored the winning goal for the Whites in the 1968 Inter-Cities Fairs Cup Final. He also won two league titles and the FA Cup with Leeds.
Now back at Leeds working in the Academy, like Bromby, Cresswell also played for both Sheffield clubs. He was at Leeds from 2005-2007 as a player and joined Sheffield United initially on loan in 2009.
