Three days after Saturday evening's goalless draw at Brighton, Leeds were heading for another 0-0 but the Whites were awarded a 91st-minute penalty after Marc Guehi blocked Liam Cooper's header from a corner with his arm.
After the intervention of VAR, referee Kevin Friend eventually pointed to the spot and Raphinha coolly converted to give Marcelo Bielsa's side their third win of the season, taking Leeds up to 15th and five points clear of the drop zone.
