Following Niklas Sule's major contract dispute with Bayern Munich, a number of Premier League clubs including Chelsea, Tottenham and Manchester United expressed interest in acquiring his services on a free transfer in the summer of 2022. In the end the German international made the switch to Bayern's Bundesliga rivals Borussia Dortmund once his contract expired in the summer.
Chelsea's interest in Sule can be dated way back to Antonio Conte's time at the helm in west London when he was scouted as a possible acquisition to re-shape and re-structure the defence in SW6 but at the time he preferred a move to Bayern from Hoffenheim.
Sule featured 171 times for Bayern over five seasons before ultimately choosing to join Dortmund on June 1 over a potential move to the Premier League. Chelsea, Manchester United and Spurs were all in desperate need of defensive reinforcements at the start of the year, especially as the Blues were set to lose both Antonio Rudiger and Andreas Christensen at the end of their contracts.
