Leeds United have already secured their first signing of the transfer window in the form of Max Wober from Red Bull Salzburg but there are numerous other players they've been linked with.
One of those is Hoffenheim striker Georginio Rutter, who has reportedly agreed personal terms with the Whites having struck a record signing fee of €28m (£24.7m) which could stretch to €40m (£35.3m) with add-ons.
The 20-year-old is one of Europe's hottest prospects after netting 11 times and providing eight assists across his first two seasons with the Bundesliga outfit and is on the cusp of being the newest addition at Elland Road.

Rutter has only previously worn the number 33 at Hoffenheim, however that number is already taken within the Leeds squad by Norwegian left-back Leo Hjelde.
He has also worn number 9 when starring for the France international Under-19 and Under-20 youth teams but used number 18 during his two appearances in the Under-21s.
Both of those are taken however by Patrick Bamford and Darko Gyabi, but his number while playing for Stade Rennais at the start of his career was 35, which is not taken by any current member of the Whites squad - having last been used by Charlie Cresswell who is out on loan.
The available shirt numbers that would be realistic for an incoming attacking player to wear are 17, 20, 24, 26, 27, 28 or his old shirt number of 35.
Numbers 17 and 20 were both most recently used by attacking players in the forms of Helder Costa and Dan James, while the numbers in the mid-to-late 20's have all been used by various positions.
Historically, the number 27 was used by legendary Premier League striker Robbie Fowler from 2001-2003 while he was a Leeds player, giving further weight to that selection.
However, if the Whites have spent a record transfer fee on Rutter, it's more likely they'll use a much lower number on him to 'certify' his significance, meaning that 17 is the most likely option for him.
