Mateusz Klich is one of the first players that come to mind when reflecting on the Marcelo Bielsa era at Leeds United. Although the Argentine began to use Klich from the bench more in the Premier League, Bielsa named the Pole as a starter in all but one game in the two years Leeds spent in the Championship under him.
The one game he missed was the game immediately after Leeds had secured promotion back to the Premier League, with Klich appearing to have partied harder than any of his teammates and him rotated out of the side. The midfielder's celebrations in the empty stands and his breakdancing on the pitch after the Whites defeated Derby on that day endeared him to Leeds fans even further, while his social media accounts were essential viewing across the promotion weekend.
Klich's journey to a cult hero under Bielsa was a particularly surprising one, given that the former FC Twente man had been loaned out from the club mid-way through his first season. He made only four appearances under Thomas Christensen and his performance in an away loss against Cardiff City, in which he slipped over in the run-up to Cardiff scoring, seemed to lose him the trust of his manager.
