Now that the 2017/18 season is over and the transfer window is open, it is time for Leeds United to start thinking about their summer business and how to improve for next year.

Under both Thomas Christiansen and Paul Heckingbottom, Leeds stumbled into an underwhelming mid-table finish in the Championship and will be looking to improve upon this and launch a bid for the play-offs.

But ahead of next season, there is still a lot of uncertainty surrounding Paul Heckingbottom's future as Leeds manager.

Heckingbottom joined from Barnsley and did not have a transfer window to work with, but many Whites supporters pointed to his tactical weaknesses.

Leeds fans are yet to be convinced that Heckingbottom is the right man for the job but he needs to get them onside with one or two marquee signings which show his intent as manager.

Here are some deals that Heckingbottom needs to complete early to prove his doubters wrong and endear himself to Leeds fans.

A number of last summer's arrivals have been flops and Wiedwald is no exception.

The German goalkeeper has struggled to adjust to life in England and Leeds should actively look to move him on, despite him still having two years left on his current deal at Elland Road.

With the emergence of Bailey Peacock-Farrell, Wiedwald is unlikely to get much game time and Heckingbottom should look to send him back to Germany early in the window so Leeds fans know he is not going to mess around with last season's deadwood.

Bartley is the man that every Leeds fan wants.

The 26-year-old formed one of the most formidable centre-back partnerships in the Championship last season during his loan spell at Elland Road and his return could even get former partner Pontus Jansson back to his best.

Leeds may now face a battle to sign him after Swansea were relegated but they should signal their intent by launching a concrete offer for the dominant centre-half.

After watching Pierre-Michel Lasogga, Caleb Ekuban and Jay-Rot Grot all fail in front of goal, a striker needs to be at the top of Heckingbottom's wishlist.

Leeds have been linked with Abel Hernandez, who is a free agent after leaving Hull City, and this would be a phenomenal signing.

The 27-year-old Uruguay international is a proven goal scorer at Championship level, scoring eight in eight starts after returning from injury and he previously netted 20 in the second tier - he could be the man Leeds fans have been waiting for since Chris Wood left.
