Phil Hay takes a closer look at those first-team recruits who arrived in West Yorkshire in recent seasons.
A move completed on deadline day for an upfront fee of 2.5m. Roberts arrived from West Brom on a four-and-a-half-year contract, six months before his deal at The Hawthorns expired.
Cardiff City made a concerted bid to land him but Leeds were equally willing to meet Middlesbroughs initial valuation of 3m and the midfielder accepted the offer from Elland Road.

The left-back had pedigree in Belgium, where he had picked up medals with Club Brugge, and Leeds spent 1.5m to bring him to England. The transfer was not a success.
Leeds teed up this signing in advance of the window opening and paid Gamba Osaka 500,000 for Ideguchis signature. He was highly-rated and a Japan international but it is doubtful that he will ever make a first-team appearance.
The Elland Road club made hard work of the 2017 winter window and both of their signings arrived at the death. Swansea Citys Barrow was one of them, a player who had worked under Garry Monk previously. He hardly played.
Pedraza was 20 when he signed on a temporary basis from Villarreal and the winger had something about him. Had United been promoted, an agreement was in place for him to sign for 10m. Real Madrid are now being linked with him.
A no-brainer to keep the Spaniard after a loan spell from Al-Arabi in Qatar. Still going strong at Elland Road, at the age of 33.
A 575,000 recruit from Brentford and an attempt by Steve Evans to strengthen his midfield. Evans departure the following summer spelled the end of Diagouragas career at Leeds, almost before it had started.
Cut short a loan at Huddersfield to switch to Leeds from parent club Middlesbrough on a temporary basis. Scored a peach of a goal on his debut against Rotherham but made a meagre impact overall.
A name which brings to mind the nightmare of January 2015, when Leeds were under an FFP transfer embargo. The Albanian, who was loaned from Catania in Italy, didnt look good enough on paper and wasnt good enough in the flesh.
Signed on loan from Palermo without undergoing a medical. The chickens came home to roost when it transpired that NGoyi had a chronic thigh problem.
Like NGoyi, a loanee from Palermo but a much better piece of business. The centre-back joined permanently in the summer and is currently playing in the Premier League with Cardiff City.
Taken on loan from Hull City with a view to a permanent move. Had the makings of a handy signing but wasnt and Leeds tried without success to back out of a full-time contract agreed with him when he first arrived.
A winger who had shown touches of magic at Reading but became a figure of fun during his loan from the Madejski Stadium. Made his Leeds debut in a 6-0 thrashing at Sheffield Wednesday.
Cost a small six-figure fee when United converted a loan from Southend into a permanent transfer. Went onto play four times for the club and is now in non-league. Money well spent.
Widely reported to have been a transfer arranged by then board member Salim Patel with the help of El-Hadji Diouf. Loaned from Zulte Waregem in Belgium with a view to a permanent deal, which Leeds unsurprisingly never concluded.
An experienced midfielder and one of Neil Warnocks old boys from Sheffield United who signed from Stoke after completing a steady loan.
Still a contentious transfer even now. Luciano Becchio went to Norwich City late in the window. Morison and 200,000 came the other way. No-one in Leeds has ever quite forgiven that trade off.
A decent capture on a free transfer from Aston Villa. Warnock held down a place at left-back for two years before Massimo Cellino sanctioned his exit to Derby in January 2015.
A prodigious talent from Everton who was unable to make anything of a loan at Elland Road, largely because Neil Warnock was reluctant to play him.
Arrived on January 31 from Tottenham while Simon Grayson was manager. Saw Leeds sack Grayson the following day. Moved back to White Hart Lane within a month.
Pugh had already been on loan at Elland Road but United paid Stoke City around 500,000 to hand him a two-and-a-half-year deal.
The return of the prodigal son, on loan from Aston Villa. Alas, Delph featured five times, injured ankle ligaments and promptly underwent surgery. Season over.
Symptomatic of the rut Leeds were in. United loaned him from Spurs at the start of the January window but by February, Townsend had asked to leave and join Birmingham Citys bid for the play-offs instead.
Leeds went stateside for Rogers, signing the midfielder from MLS club Columbus Crew. He was released the following year and briefly retired from the game after announcing that he was gay. Resumed his career at LA Galaxy.
A Manchester City goalkeeper who Leeds recruited on a half-season loan. Not a face you would remember.
Had done well on a temporary switch from Bolton and became a permanent recruit in January 2011. His form was up and down and he later had a huge fall-out with Simon Grayson.
